Talk:McMurry reaction

It is unclear to me why user V8rik insists on reverting my edit. Clearly he knows more about wikipedia policy. I just though that I would correct a factual inaccuracy. The version V8rik reverted to states that the graphic is inaccurate in the main text. Is the factual inaccuracy even in dispute if the main text disagrees with the graphic? What V8rik labels as vandalism is simply me removing incorrect information. This is not a nuanced point, the "simplified cartoon" is laughably wrong. However, if incorrect information cannot be removed from wikipedia, errors will abound. My interest in "getting involved" are limited. But, I am left wondering, is this guy even a chemist? — Preceding unsigned comment added by 128.32.57.198 (talk) 22:28, 15 March 2012 (UTC)


 * very typical of anon users: the insults. I have removed this article from my watchlist V8rik (talk) 16:53, 16 March 2012 (UTC)


 * V8rik, I merely felt that labeling my edit as vandalism was an unjustified action. Here, I sought to express this viewpoint in a clear and unambiguous way. My apologies if you were able to construe personal insults from my words.  — Preceding unsigned comment added by 128.32.57.198 (talk) 21:18, 16 March 2012 (UTC)

New picture molecular motor synthesis
I changed the picture of the synthesis of Feringa's synthetic molecular motor. The old one was wrong for several reason: 1) Some double bonds were drawn as single bonds, thereby destroying the aromaticity of the molecule. 2) Only one enantiomer was drawn for both the starting ketone as well as the product olefin, implying this reaction was performed with retention of the stereochemistry of the ketone. This, however, is not the case -- the product of the reaction is a racemate. 3) The McMurry reaction using TiCl4 was not performed on this exact molecule, only on structurally similar ones. I therefore chose to display the synthesis of the 5-membered ring molecular motor, which was published in 2003 in J. Am. Chem. Soc. TommyCP (talk) 15:45, 21 February 2010 (UTC)
