"However, it has a negative charge on terminal carbon and oxygen atom" - it has a negative charge on both? Would it be a dianion in this case? Ephineprine (talk) 16:17, 18 December 2023 (UTC)


 * I was about to say that there is negative charge on either carbon atom or oxygen atom because of resonance structure. I rephrased it for clarity. Hienn211 (talk) 19:12, 18 December 2023 (UTC)

"Its resonance structures illustrate major electronic structure." - Would you explain a bit more about what major electronic structure means? Ephineprine (talk) 16:18, 18 December 2023 (UTC)


 * I removed this sentence and added more details on previous sentence to discuss more about resonance structure. I realized that this sentence does not connect with previous sentence fluently. Hienn211 (talk) 19:16, 18 December 2023 (UTC)

In the lead section, "it has a negative charge on either terminal carbon and oxygen atom" is confusing. Seems like the connecting word should be "or" instead of "and". OneMustImagineAGradStudentHappy (talk) 06:42, 19 December 2023 (UTC)


 * Thank you the catch Hienn211 (talk) 14:43, 19 December 2023 (UTC)

"Later in their studies, the ketenyl anion product upon carbonylation can be selective by chanhging electron-withdrawing ability on a certain leaving group and Lewis acidity of coordinated alkali metal cation" - Would be good to be more specific on the leaving group and alkali metal, and what changes are induced respectively Ephineprine (talk) 16:49, 18 December 2023 (UTC)


 * I added more details on trend of leaving group and Lewis acidity on alkali metal cation in selective carbonylation reactions. Hienn211 (talk) 21:20, 18 December 2023 (UTC)

Minor typo - changhing Ephineprine (talk) 16:25, 18 December 2023 (UTC)


 * fixed it! Hienn211 (talk) 19:20, 18 December 2023 (UTC)

In the synthesis section, toward the end of the first paragraph, did you mean triphenylphosphine instead of "tryphenylphosphine"? OneMustImagineAGradStudentHappy (talk) 06:44, 19 December 2023 (UTC)


 * I fixed it Hienn211 (talk) 14:43, 19 December 2023 (UTC)

Citation for first paragraph would be good Ephineprine (talk) 17:15, 18 December 2023 (UTC)


 * I added an appropriate reference for describing resonance structure. Hienn211 (talk) 03:26, 19 December 2023 (UTC)

"Inoue's silca-ketenyl anion product, shown in Figure 2, had Wiberg bond index of 1.68 and 1.76 for Si-C bond and C-O bond, respectively." - What is the signficance of this? Ephineprine (talk) 17:12, 18 December 2023 (UTC)


 * I was intended to explain that bond indices demonstrates Si=C=O structure, which resembles ketenyl anion structure. I added an sentence to explain the meaning of the bond indices in this particular examples. Hienn211 (talk) 03:35, 19 December 2023 (UTC)

In the structure section, in the second paragraph, I believe Inoue's "silica-ketenyl" should contain an "i" in silica. OneMustImagineAGradStudentHappy (talk) 06:45, 19 December 2023 (UTC)


 * fixed it Hienn211 (talk) 14:45, 19 December 2023 (UTC)

In Figure 4, the center nitrogen atom in the first compound seems to have 10 electrons in its shell. Is that possible? OneMustImagineAGradStudentHappy (talk) 06:46, 19 December 2023 (UTC)


 * It has to be 8 electrons. I fixed the structure of the compound. Hienn211 (talk) 14:52, 19 December 2023 (UTC)

Reactivity

"Not only at the central carbon, the carbon atom between central carbon and oxygen atom can also be functionalized upon electrophilic substitution." - Is there a term for this carbon? To enhance understanding Ephineprine (talk) 17:23, 18 December 2023 (UTC)


 * I did not find proper term to describe a specific carbon in ketene functional group. I revised this sentence to specify which carbon I discussed. It would be great if there is a appropriate or proper term describing a specific carbon in ketene. Hienn211 (talk) 03:45, 19 December 2023 (UTC)

"These products requires CO and substrates of interests, which highlight new synthetic pathways of organic compounds without extreme conditions." Under what conditions are these reactions run? Ephineprine (talk) 17:23, 18 December 2023 (UTC)


 * They run at room temperature. I added more description on this sentence. Hienn211 (talk) 04:00, 19 December 2023 (UTC)

Citation for this paragraph - I think it should be Gessner (4) - would be good Ephineprine (talk) 17:23, 18 December 2023 (UTC)


 * Added it! Hienn211 (talk) 04:01, 19 December 2023 (UTC)
