The synthesis of new PCP (“pincer”) polydentate acceptor ligands is described. The versatile chlorophosphine precursor 1,3-C6H4(CH2PCl2)2, was prepared and converted to 1,3-C6H4(CH2P(OPh)2)2, and then perfluoroalkylated by Ruppert's reagent, CF3SiMe3, to form perfluoromethyl PCP phosphine, 1,3-C6H4(CH2P(CF3)2)2. An initial survey of platinum and iridium coordination chemistry for this new PCP ligand will be presented.
