The rearrangement reactions of silylated alcohols bearing the highly strained structures of cyclopropene and cyclopropanol connected in adjacent positions have been studied under ZnI2- and Rh(I)-catalyzed conditions. The results show intriguing

The Beckmann rearrangement of either syn or anti 3,4-diphenyl-cyclohexenone oxime 2a,b in polyphosphoric acid produces only one of the two possible isomeric unsaturated caprolactams 1. Under neutral conditions, only the syn oxime tosylate 9b rearranges to lactam 1, the anti oxime tosylate 9a remains unchanged. These results support earlier reports that alkyl migration is preferred over vinyl migration in the Beckmann rearrangement of unsaturated cyclic ketoximes. Structure proof of the lactam was made using deuterium exchange and HMQC nmr experiments.

It is shown that acid-catalyzed docomposition of the 1,2-dioxetane derivative, 3,3-dimethyl-7,7-diphenyl-1,2-dioxaspironona-5,8-diene, obtained from 1-isopropylidene-4,4-diphenyl-2,5-cyclohexadiene, gives 1-methyl-1-(o-terphenyl-4'-yl)ethyl hydroperoxide, bisperoxide, 1-(1-hydroperoxy-1-methylethyl)-4,4-diphenylcyclohexa-2,5-dien-1-ol, and o-terphenyl-4'-ol, along with the usual dioxetane-scission product, 4,4-diphenyl-2,5-cyclohexadienone.The distribution and yield of these products depend on acidic agents and/or conditions employed.
