User talk:Hisashi Bob Iwahashi/Acetate Pyrolysis

Other ways to lower eliminatioin temperatures: Formate pyrolysis might go at a lower temperature, but formate esters are difficult to make. Formyl chloride dissociates to HCl and Carbon monoxide. I believe, if triflouro acetyl chloride is used to make the ester of the alcohol, the temperature of eliminatioin should decrease. The Oxygen-Carbon bond to the carbonyl carbon is shorter,stronger than the O-C bond on the other side. This would mainly be due to the inductive effects through the sigma bonds. It is the manifestation of Flourine's electron affinity. Trichloro acetyl chloride may also work, but the electron affinity is weaker and the Chlorines are larger. This may interfere with the cyclic transitioin state stereo-chemically. The advantage of trichloro acetate is cheaper cost. Tosylates may also undergo pyrolysis reactioins. Triflourate is a very good leaving group. It is mesolate with the hydrogens replaced by Flourine. Chlorine instead of Flourine would again be more cost effective. The reason these acid esters would eliminate at lower temperatures is that the corresponding acid is more acidic. The O-C bond is weaker if more acidic acid is used. 38.184.1.101 (talk) 00:48, 13 October 2009 (UTC) Hisashi Bob Iwahashi
