摘要：

The synthesis and characterization of iridium complexes containing the PCy(2)biPh ligand (PCy(2)biPh = 2-(dicyclohexylphosphino)biphenyl), is described. Chloride abstraction from (COD)Ir(PCy(2)biPh)Cl with Na(BArP)(4) affords [(COD)Ir(PCy(2)biPh)][B(Ar-F)(4)] (1, ArF = 3,5bis(trifluoromethyl)phenyl). Heating 1 in benzene results in dehydrogenation of one of the cyclohexyl groups on the phosphine ligand with COD serving as the hydrogen acceptor, leading to the new complex 2, with benzene coordinated in an eta(6) fashion to the metal center. Complex 1 reacts with H-2 to produce the Ir(III) dihydride complex [(PCy(2)biPh)IrH2][B(Ar-F)(4)] (3). Initial studies of transfer dehydrogenation and attempts at benzene hydrogenation using 1 and 3 are described.
