Microwave Assisted Facile Cleavage of 2,4-Dinitrophenylhydrazones to the Corresponding Carbonyl Compounds with N,N′-Dibromo-N,N′-1,2-ethanediylbis(p-toluenesulphonamide)

Abstract

Deprotections of 2,4-dinitrophenylhydrazones to their corresponding carbonyl compounds have been carried out in good yields by using N,N′-dibromo-N,N′-1,2-ethanediylbis(p-toluenesulphonamide) (BNBTS, 2) under microwave irradiation.
