6,7-Benzoelassovalene has been synthesized from benzocyclobutene and 1,4-cyclohexadiene-1,2-dicarboxylic anhydride. This crystalline white solid undergoes rapid decomposition when exposed to air, but can be handled under an argon atmosphere. An x-ray

Stereospecific [3,3] shift of a cyclobutene ring involving photofragmentation of a 1,8-bishomocubane as the relay

Publikováno v: Journal of the American Chemical Society. 99:2815-2816

A novel photorearrangement mediated by a 1,8-bishomocubane derivative in which a suitably positioned benzene ring serves as the internal activator is reported. The key feature of the process is a stereospecific (3,3)cyclobutene ring transposition whi
