Extra citation
Hello, there's no need to add an extra ref when there's already a high-quality citation, like you did at Butylated hydroxytoluene, so I removed it. If there was a good reason to add it and you have no conflict of interest relating to the authors, I'd be happy to put it back. Graham87 (talk) 19:40, 9 May 2024 (UTC)


 * Thank you for going over the citations! I added the citation because the article demanded a nonprimary citation in that place. I am not sure if it has already been fixed, so I added another citation anyways. However, if the existing citation is indeed high quality, I am happy to remove my citation. Pygos (talk) 01:28, 10 May 2024 (UTC)
 * Ah, I nevver noticed that tag there. I've now removed it since you provided a secondary source; you should remove such tags also when you fix issues like that. Sorry for the bother. Graham87 (talk) 08:29, 10 May 2024 (UTC)

License tagging for File:Chromium pentoxide in ethyl acetate.jpg
Thanks for uploading File:Chromium pentoxide in ethyl acetate.jpg. You don't seem to have indicated the license status of the image. Wikipedia uses a set of image copyright tags to indicate this information.

To add a tag to the image, select the appropriate tag from this list, click on this link, then click "Edit this page" and add the tag to the image's description. If there doesn't seem to be a suitable tag, the image is probably not appropriate for use on Wikipedia. For help in choosing the correct tag, or for any other questions, leave a message on Media copyright questions. Thank you for your cooperation. --ImageTaggingBot (talk) 04:30, 10 May 2024 (UTC)


 * Hi Pygos. In addition to the bot's message above, I would add that this is a nice image that you would have been better to upload to Wikimedia Commons, with a license like CC BY SA 4.0 (the default), or PD if you don't mind people using it without attribution to you. Only images on Commons are available for other-language versions of Wikipedia to use, which is why they are best placed there. I note that this particular image is quite low-resolution. If you have a higher-resolution version available, then it would make sense to upload that but maybe you can't because you cropped the image from a larger version from your camera? If so, you should have chosen to retain exif data, which helps with the provenance of the picture. Regards. Mike Turnbull (talk) 11:02, 10 May 2024 (UTC)
 * Thank you for your suggestion! I will upload it onto Wikimedia commons. By the way, the image was indeed cropped from a larger one. Pygos (talk) 11:40, 10 May 2024 (UTC)

Welcome on board
Welcome to Wikipedia. Here are suggested readings: WP:SECONDARY and WP:COI. These guidelines say: If you have questions, many editors can offer advice. Happy editing.--Smokefoot (talk) 14:36, 11 May 2024 (UTC)
 * Wikipedia prefers citations to reviews and books, not primary journal references (tens of thousands appear annually). Citing secondary sources (reviews) is the encyclopedic style.
 * Do not cite yourself or your colleagues. It's called conflict of interest.  Many new editors cite themselves mainly.  That behavior is unacceptable.


 * Thank you! I have read these articles. Pygos (talk) 14:51, 11 May 2024 (UTC)
 * A JACS paper is not an app. Its just another academic claim.  --Smokefoot (talk) 14:58, 11 May 2024 (UTC)
 * Please pardon my ignorance, but I am confused about what comment you are replying to, but thank you anyways! Pygos (talk) 15:10, 11 May 2024 (UTC)
 * Oh, sorry. I was pointing out that
 * "==Applications==


 * "Kolbe electrolysis has found applications in converting biomass into biodiesel. It has the advantages of producing hydrogen and bicarbonate as side products.


 * "Kolbe electrolysis can also be used for grafting of carbon electrodes. "


 * These are not applications. Just 2 of hundreds of mainly academic papers on Kolbe electrolysis. Do we really want general readers to conclude that Kolbe is useful for biomass conversions? . Apologies for being so pushy and rude, but new editors and young chemists rarely understand the predicament we find ourselves in at Wikipedia-Chem: a tidal wave of literature.--Smokefoot (talk) 16:04, 11 May 2024 (UTC)
 * Ah, I see, I will try to include secondary sources as well. Happy editing! Pygos (talk) 01:13, 12 May 2024 (UTC)
 * I dont want to come across as a complete hypocrite. For specialized topics like tin triphosphide, chromium(VI) oxide peroxide, there is often no option than to cite primaries. But for big topics, I and others strive for secondary (reviews), or better still "tertiary", i.e. textbooks (reviews of reviews). For editing organic, inorganic, and industrial themes, my go-to sources are textbooks/encyclopedia residing on my laptop: March's organic, Greenwood and Earnshaw's inorganic, Ullmann's Industrial Chem.   --Smokefoot (talk) 13:58, 12 May 2024 (UTC)
 * I see. I happen to have read the first book, and I also have access to the other two. I will try to consult the most reliable sources possible. As always, thanks for guiding me on citing sources! Pygos (talk) 05:36, 13 May 2024 (UTC)
 * Greetings, Smokefoot!
 * I am currently having some trouble in adding organic reaction schemes onto articles, with the questions specified below:
 * 1, I am unsure of what format to use for the reaction schemes. I am currently editing Wikipedia on a mobile device (Android). I have read the following articles:Manual of Style/Chemistry/Structure drawing and Molecule editor, and it seems that there are no listed chemical editing devices suitable for Android. I currently use Kingdraw to draw chemical reaction schemes. I am not sure if that is acceptable. A sample of what Kingdraw reaction schemes look like is shown below:
 * [[File:Kingdraw azulene screenshot.jpg]]
 * (Note:this image was taken via screenshot, I am not sure if this is acceptable for Wikipedia articles)
 * 2, I am unsure of what copyright status should the reaction schemes from literature (like the one above) be published under. Can they be uploaded onto Wikimedia Commons, or are they considered others work and not of Public Domain even if I redraw them? From the articles that I have seen, it seems that the reaction images are all under the Creative Commons licenseship and labeled as "own work".
 * I highly appreciate your efforts in responding these questions above.
 * Sincerely, Pygos Pygos (talk) 12:11, 14 May 2024 (UTC)
 * Kingdraw azulene screenshot.jpg
 * Pyrgos. I noticed your recent additions to Azulene. The use of .jpg files makes for serious problems, as indeed can be seen above in this thread with the screenshot, which in my full-size computer monitor sends the image off the right of the screen. We much prefer .svg files for chemical diagrams and .png files are also acceptable but less good as they don't scale as well on different devices. If you use .jpg, then you must include the "thumb" parameter as I have done here on the right. I could work with you to produce the chemical drawings needed: for example by collaborating in one of your sandboxes, if your Android device can't use any of the drawing programs mentioned at MOS:CSDG. Thoughts? Mike Turnbull (talk) 11:14, 15 May 2024 (UTC)
 * I've now looked at the website for Kingdraw. They suggest that it can produce industry-standard output files for the drawings. Does that include the sketch file format (.skc) originally specified by Molecular Design Limited or Microsoft's enhanced metafile .emf? If so, then converting these to .svg is easy for me to do and collaboration would be simple. Mike Turnbull (talk) 11:28, 15 May 2024 (UTC)
 * Thanks for pointing out! I have found that kingdraw can generate files of kdx mol molV3000 cdx png jpg formats. Which formats are acceptable? I will also revert my edits on azulene temporarily to prevent confusion. Pygos (talk) 12:13, 15 May 2024 (UTC)
 * As far as I can tell, .kdx files are Kingdraw's own proprietary format, so not useful external to that program. Mol and molV3000 are now open source (they were invented by MDL) but only work for a single molecule. ChemSpider, for example, allows you to download any molecule from their database in that format, so you would never need to draw from scratch anything you found on Chemspider. CDX files are ChemDraws proprietary format which can't be used directly within Wikipedia but would work as a way to share files between ourselves by email, since I can convert them to .skc files and hence to .svg. .png and .jpg are standard for any image, not just chemistry but lose all chemical connectivity information, so while you can go .skc / .cdx / .kdx to .png or .jpg, it is impossible to go the other way! Bottom line: if you are uploading files for use in Wikipedia, you should always use .png files for chemistry, never .jpg, and make sure you set pixel widths (or use "|thumb") when you place the diagram into a Wikipedia article. As I mentioned before, this is less than ideal because as Help:Pictures says, we prefer not to force images to have a specific size as they don't always look good on all the devices used by readers. SVG files are vector graphics and have many advantages: they are usually very small and they can be edited in a text editor or by free software such as Inkscape. I have uploaded dozens of chemistry files as .svg conforming to MOS:CSDG: see my files on Commons. The chemistry ones use ACS settings as specified in our manual of style and look very good even when viewed at small size. For now, I suggest you go back and delete all your .jpg and upload .png instead. Note also that Commons is chasing you about copyright issues. You must make it clear where you got the image from and whether it is your own work (which means you drew it yourself in some image-generating program) or is a derivative of a published work: the latter only being OK if you quote the source and can confirm that the source stipulates it is released under a valid CC license (as many but not all modern journal articles are). Apologies that this is a long post but I'm afraid the learning curve on Wikipedia is steep! Mike Turnbull (talk) 13:32, 15 May 2024 (UTC)
 * Thanks for the detailed explanation! I will try my best to adhere to the standard practices of Wikipedia. I will put my sandbox here so we can communicate more easily:
 * User:Pygos/sandbox Pygos (talk) 16:07, 15 May 2024 (UTC)
 * Fine. No hurry. Note that you can contact me by email (via my userpage) if we end up needing to exchange files. Mike Turnbull (talk) 17:30, 15 May 2024 (UTC)
 * Greetings, Smokefoot! I have another minor question on citing sources. For instance, if I were to cite Sciencemadness Wiki, a tertiary source, should I cite the wiki itself or the citation link on the wiki which would lead to a secondary source? I appreciate your reply. Pygos (talk) 03:04, 27 May 2024 (UTC)
 * I think that Smokefoot and I will have similar views, which is that the clue is in the name. Wikis are never reliable sources in themselves, although they may cite ones that are. They are user-generated and like IMDb, even if they are extensively used by readers they have no guarantee of accuracy e.g. because at any given moment a vandal may have inserted misleading information. I took a look at a random page on Sciencemadness and was given this one on potassium hydroxide which has no references at all, despite clearly being a very well researched and important compound! In other respects that page was similar to potassium hydroxide, especially in the Chembox. Draw your own conclusion: mine is that Sciencemadness should not be touched with a ten foot pole. Mike Turnbull (talk) 11:00, 27 May 2024 (UTC)
 * Hmmm...I see your point. Thanks for helping out! Pygos (talk) 13:30, 27 May 2024 (UTC)

Thiourea and squaramide, etc
Thank you for you help with the organic catalysis articles. Some are dated. Most consist mainly of primary references: the area is so mature that our articles could be rely almost exclusively on books and major reviews. Many of the articles imply applications when in fact almost none exist. Some promote various "pioneers". So, good luck dealing with this huge, sprawling topic.--Smokefoot (talk) 13:31, 6 June 2024 (UTC)
