Niobium pentachloride: An efficient catalyst for the selective acetylation of amines and thiols under mild conditions

A variety of amines and thiols were reacted smoothly with acetic anhydride to give the corresponding acetylated products in excellent yields catalysed by niobium pentachloride. All the reactions were performed at room temperature while using dichloromethane as solvent.
