Fe(NO3)3·9H2O-mediated visible-light photocatalysis for the nitration of cyclobutanols: access to functionalized nitrocyclobutenes

Abstract

A straightforward method for the synthesis of nitrocyclobutene derivatives from cyclobutanols with Fe(NO3)3·9H2O has been developed via a visible-light photocatalytic radical addition reaction. The reaction utilizes Fe(NO3)3·9H2O as the nitro source and RFTA as the photocatalyst, showing good functional group tolerance and furnishing the desired products in moderate to excellent yields. Preliminary mechanistic studies suggested that the nitro radical was involved in the reaction process.
