The three-component reaction of benzotriazoles, aldehydes, and alkynes has been carried out for the first time using zinc bromide as a catalyst. The corresponding propargylbenzotriazoles are formed in high yields (79-97%) within 6-10 hours.

A one-pot three-component synthetic route toward 5-allyl-1,2,3-triazoles using copper(i) acetylide has been developed, which allows further transformation to important tricyclic scaffolds.
