BUTYLTRIPHENYLPHOSPHONIUM TETRAHYDROBORATE (BTPPTB) AS A SELECTIVE REDUCING AGENT FOR REDUCTION OF ORGANIC COMPOUNDS

Abstract

Butyltriphenylphosphonium tetraborate (BTPPTB) (1) has been found to be a selective and versatile reducing agent. The reagent in dichloromethane solution or under solvent-free conditions is very useful for reduction of aldehydes, ketones, carboxylic acid chlorides, aryl azides, and aroyl azides to the corresponding alcohols, amines and amides, respectively.
