An organoselenium-catalyzed N1- and N2-selective aza-Wacker reaction of alkenes with benzotriazoles

Abstract

An organoselenium-catalyzed N¹- and N²-selective aza-Wacker reaction of alkenes with benzotriazoles is reported, which provides easy access to N¹- and N²-olefinated benzotriazole derivatives. The wide substrate scope, good functional group tolerance, and facile scale-up of this method are expected to promote its potential application in synthetic chemistry. A preliminary mechanism is proposed to explain the N¹- and N²-selectivities.
