Nucleophilic Addition of Azoles to Triphenyl-(phenylethynyl)phosphonium Bromide and Base Hydrolysis of the Addition Products

摘要

Reactions of pyrazole,3,5-dimethylpyrazole,imidazole,and 1,2,4-triazole with triphenyl(phenyl-ethynyl)phosphonium bromide gave the corresponding 2-azolyl-2-phenylethenyl(triphenyl)phosphonium salts.Base hydrolysis of the addition products led to the formation of 2-azolyl-l,2-diphenylethyl(diphenyl)phos-phine oxides.
