使用NIOBIUMCHLORIDE is used as reductively couples imines and nitriles.
製造方法Reduction of NbCl5 with H2 at 2 atm. (generated when the tube is filled at STP, sealed and then heated). The reaction does not go to completion and NbCl5 and NbCl4 must be separated by sublimation.
純化方法NIOBIUMCHLORIDE is Purified by filter and wash with THF and dry under vacuum.
