Abstract

Alkynyl(phenyl)iodonium salts react with benzotriazole ion prepared from benzotriazole and potassium t-butoxide to give 1-alkynylbenzotriazoles in good yields, indicating that the alkynyliodonium salts can be used for direct alkynylation of benzotriazole.

Reaction of alkynyl(phenyl)iodonium tosylates with benzotriazole ion gives 1-alkynylbenzotriazoles.
