We report the preparation of 1-(1-alkenyl)benzotriazoles from alkenyl (phenyl)iodonium salts and benzotriazole. The reaction offers a simple and convenient route for the stereoselective synthesis of 1-(1-alkenyl)benzotriazoles. In addition, present method is particularly efficient for preparing 1-(1-alkenyl)benzotriazoles with amino-, acyl- and alkoxycarbonyl substituents, which were difficult to prepare by conventional methods.
