Abstract

Abstract: Irradiation of 4, 4-dicyclopropylcyclohexenone (5) in tert-butyl alcohol affords only 6, 6-dicyclopropyl-bicyclo [3. lO] hexan-2-one (6) and 3-(dicyclopropylmethyl)-2- cyclopentenone (10). The absence of detectable amounts of cyclopropyl migration products is rationalized most readily in terms of a reacting excited state having radical character. ne of the more pronounced mechanistic di-goes predominant 4, 3-phenyl migration, without ...
