Alkylidenecyclobutanes. Part II. The oxidation of benzylidenecyclobutane and of bis-(p-methoxyphenyl)methylenecyclobutane
Abstract
The oxidation of benzylidenecyclobutane gives rise to both rearranged and unrearranged products. The differences observed in the tendencies of alkylidenecyclobutanes and of cyclobutylmethanols to rearrange in the course of oxidations (or dehydrations) is ascribed in part to a steric effect.
