Direct amination of benzene to aniline with several typical vanadium complexes
摘要:
The liquid-phase direct catalytic amination of benzene to aniline was performed in acetic acid water solvent using a series of vanadium (Ⅲ, Ⅳ, Ⅴ) complexes with N,O-or O,O-ligands as catalysts and hydroxylamine hydrochloride as the aminating agent.The vanadium complexes exhibited much higher selectivity towards the production of aniline than NaVO3 or VOSO4. Under the optimized conditions, an aniline yield of 42.5% and a TON of 48 with a high selectivity of above 99.9% was obtained using 0.2 mmol of [VO(OAc)2] as the catalyst.
