Alkynylbenzotriazoles by direct alkynylation of benzotriazole using alkynyliodonium salts

Article abstract of DOI:10.1016/S0040-4039(98)00617-0

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.
