I, obtained. Thus, the cyanohydrin 15 clearly differs in spectral and physical properties from its trans isomer obtained by treating cyclohexene oxide with potassium cyanide. Arenesulfonyl groups are well-known one-electron acceptors." Presumably the first step in fragmentation of cycloadducts 5-9 involves electron transfer from sodium amalgam to the benzenesulfonyl group. However, the conditions employed here (2% Na-Hg at 20" C) are ...
