Abstract

The reaction of dimethyldioxirane with several alkynes gives products which are conveniently rationalized by postulating the intermediacy of oxirenes and oxocarbenes. The latter serve as precursors to H atom or methyl group migration products, as well as to cyclopropane insertion products in some cases. Alkenes, derived from some of these carbene reactions, are partially converted to epoxides.
