Chugaev elimination is a pyrolysis reaction like acetate pyrolysis. Acetate pyrolysis is an elimination of acetic acid from an alcahol that has been acylated with acetyl chloride or acetic anhydride. Upon heating the acetate takes off an hydrogen that is available next to it alpha beta elimination. The acetate and the hydrogen leaving to produce the double bond have to be cis. Since most additions to double bonds go trans, if the addition of acetic acid to a double bond if followed by acetate pyrolysis, a trans olefin can be changed to cis and vice versa. The Chugaev elimination occurs in the same manner cis. The advantage is that the reaction occurs at a lower temperature. Hisashi Bob Iwahashi (talk) 20:09, 10 October 2009 (UTC) Hisashi Bob Iwahashi
