Reaction of some aliphatic and aromatic nitriles with tungsten(VI) chloride leading to the formation of tungsten–nitrogen multiply bonded compounds
Abstract
From the reaction of WCl6 with a number of aliphatic and aromatic nitriles, compounds [WCl4(NCRCl2)]·RCN (R = Me, CH2Cl, CHCl2, CH2ClCCl2, CH2CH, CMe3, Ph, C6H4Cl-4, C6H4Me-2, or C6H4Me-4) have been isolated. These species have been characterised by analysis and n.m.r. and i.r. spectroscopy. It is suggested that these metal imido-derivatives may be intermediates in the formation of WCl4·2RCN from the reaction of WCl6 with alkyl cyanides.
