A stand-alone cobalt bis(dicarbollide) photoredox catalyst epoxidates alkenes in water at extremely low catalyst load

Abstract

Cobaltabis(dicarbollide), Na[3,3′-Co(η5-1,2-C2B9H11)2] Na[1]), is an efficient photoredox catalyst for the epoxidation of alkenes in water, at low catalyst loading and requiring short reaction times (15–30 min).
