Abstract
IT is generally believed that esters pyrolyse to give the products of cis elimination in a six-membered cyclic transition state1. Recently, however, products corresponding to a trans elimination have been shown to be formed by the pyrolysis of methyl xanthates of some substituted cyclohexanols2. The pyrolyses of xanthates and acetates of 1-alkylcyclohexanols give predominantly the more stable endocyclic olefins3, and both cis and trans elimination have been observed in pyrolyses of chlorosulphites2, and sulphoxides4.
