A facile and efficient synthesis of aryl toluenesulfonhydrazides and aryl toluenesulfonates under solvent-free conditions

Abstract

A rapid, efficient method is described for synthesis of aryl toluenesulfonhydrazides from toluene-sulfonyl chloride and substituted phenylhydrazines and for the synthesis of aryl toluenesulfonates from toluenesulfonyl chloride and substituted phenols. The procedure is simple, environmentally benign and occurs in good yields.
