Talk:(E)-Stilbene

Resveratrol and Piceid
Something is wrong with this article. What is the relation of this Stilbene with the Stilbenes Resveratrol and Piceid, if any? Disambiguation needed? 69.87.194.175 19:19, 21 November 2006 (UTC)

Biologic activity of stilbenes on mammals.
Xenoestrogenic hormonal activity, endocrine disruptivity and carcinogenity of stilbene and derivatives should be of at least some concern...--84.163.100.208 19:35, 7 May 2007 (UTC)
 * Also, the external MSDS isn't on (E)-stilbene, but 1,1-diphenylethene.--84.163.100.208 19:37, 7 May 2007 (UTC)

Fixed MSDS, also added SMILES, although these SMILES do not differentiate between the E or Z form. —Preceding unsigned comment added by 87.110.228.242 (talk) 09:25, 3 February 2008 (UTC)

Article should be split into E and Z-stilbene ? - maybe re-merge
Article should be split into cis-stilbene and trans-stilbene? They can reference each other. Don't really think it makes sense to have an infobox in effect to trans-stilbene, given for example how different the melting points are.


 * No, it should not be split, trans- and cis- isomers can be made of almost every molecule that has one or more double bonds. They all have slightly different melting points, boiling points, heats of hydrogenation, stabilities and uses. This is just one property of the isomer. —Preceding unsigned comment added by Kailuasurfing (talk • contribs) 02:39, 22 January 2009 (UTC)


 * Agree, it should not be split. Sadly it has been, leaving both containing ambiguity and duplication. [rare] candidates for (re)merge ? or perhaps we move common content back to stilbene and leave E & Z for any specifics ? - Rod57 (talk) 13:25, 17 February 2017 (UTC)

Derivatives and uses - ambiguous
Derivatives and uses section needs sources and is not clear it is talking about E/trans or a mixture. -- Rod57 (talk) 13:44, 17 February 2017 (UTC)

Shouldnt this article be titled be cis stilbene?
My understanding is that cis and trans are preferred descriptors when there are only two kinds of substituents on the alkene. Also, practicing chemists call this stuff cis-stilbene, so there is a possible argument made for common usage. --Smokefoot (talk) 14:37, 7 June 2015 (UTC)

Steric interaction of cis-form
Wont this lead to two Enantiomers of the cis-form ? (doesnt seem to fit definition of Atropisomer) - Rod57 (talk) 13:54, 17 February 2017 (UTC)

photoisomerisation
Optical_brightener says the trans-form absorbs UV (and emits blue) and converts to the optically inactive cis-form. Worth noting if verifiable ? Does that suggest trans- or cis- is more stable (lower energy) ? - Rod57 (talk) 14:13, 17 February 2017 (UTC)
