资源简介：
The
synthesis and characterization of iridium complexes containing
the PCy2biPh ligand (PCy2biPh = 2-(dicyclohexylphosphino)biphenyl),
is described. Chloride abstraction from (COD)Ir(PCy2biPh)Cl
with Na(BArF)4 affords [(COD)Ir(PCy2biPh)][B(ArF)4] (1, ArF = 3,5-bis(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
η6 fashion to the metal center. Complex 1 reacts with H2 to produce the Ir(III) dihydride complex
[(PCy2biPh)IrH2][B(ArF)4] (3). Initial studies of transfer dehydrogenation and
attempts at benzene hydrogenation using 1 and 3 are described.
