An organoselenium-catalyzed N- and N-selective aza-Wacker reaction of alkenes with benzotriazoles.

An organoselenium-catalyzed N- and N-selective aza-Wacker reaction of alkenes with benzotriazoles is reported, which provides easy access to N- and N-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 N- and N-selectivities.
