A novel approach to the stereoselective synthesis of (E)-1- (1-Alkenyl)benzotriazoles

The Horner-Wadsworth-Emmons olefination of diethyl-(1- benzotriazolmethyl)phosphonate by means of aldehydes was found to be a convenient method for the stereoselective preparation of (E)-1-(1-Alkenyl)benzotriazoles.

The Chemistry of N-Substituted Benzotriazoles. Part 1. 1-(Chloromethyl)-benzotriazole

The N-chloromethyl group of 1-(chloromethyl)benzotriazole undergoes nucleophilic substitution by carbon, nitrogen, phosphorus, oxygen, and sulphur nucleophiles. α-Lithiation was achieved in high yield in 1-phenylthiomethyl-, 1-phenylsulphinylmethyl-, and 1-(phenylsulphonylmethyl)benzotriazoles and the lithio derivatives reacted with a variety of electrophiles.New benzotriazolium salts were prepared by quaternization of the N-3 nitrogen with methyl iodide.
