The formation of [Ir(CO)Cl2(PEt3)2(NF2)] and its rhodium analogue: complexes containing the novel difluoroamido ligand
Abstract
Chlorodifluoroamine reacts at 190 K in CH2Cl2 with [M(CO)Cl(PEt3)2](M = Ir or Rh) to give [M(CO)Cl2(PEt3)2(NF2)], characterised by 19F and 31 P n.m.r. spectroscopy (the 15N derivative was also obtained for M = Ir); the novel complexes decompose in solution at temperatures above 240 K, the products of decomposition including N2F4.
