N,N-Dialkylalloxans - a new class of catalyst for dioxirane epoxidations

Article abstract of DOI:10.1016/S0040-4039(99)01610-X

N,N-Dimethyl- and N,N-dibenzylalloxans 1a and 1b have been prepared and used as novel dioxirane catalysts for the epoxidation of a range of di- and tri-substituted alkenes in good to excellent yield. The dibenzylalloxan 1b can be recovered in high yield with no evidence of catalyst decomposition.
