Synthesis of copper(I) ?-diketone complexes

At room temperature, the reaction of metallic copper powder with 2-thenoyltrifluoroacetone (tfac) and selected phosphine ligands gives the new copper(I) complexes [Cu(PPh3)2(tfac)] (1), [Cu(dppm)-(tfac)]2 (2), [Cu(dppe)(tfac)]2 (3), [Cu(dppp)(tfac)](4), [Cu(dppb)-(tfac)]2 (5), Ph2P(CH2)nPPh2 [n = 1 (dppm), 2 (dppe), 3 (dppp), 4 (dppb)]. These complexes have been characterized by physicochemical and spectroscopic methods. X-ray structure analysis of 1 and 3 shows that tfac behaves as a chelating ligand and dppe coordinates as a bridging bidentate ligand to Cu(I) atoms in the Cu(I) complexes.

Direct synthesis of copper(I) β-diketone complex containing bis(diphenylphosphino)butane

At room temperature the reaction of metallic copper powder with 2-thenoyltrifluoroacetone (tfac) and bis(diphenylphosphino)butane (dppb) gives directly the binuclear β-diketone copper(I) complex [Cu(dppb)(tfac)] 2. The complex has been characterized by X-ray analysis. It shows that 2-thenoyltrifluoroacetone behaves as a chelating ligand and dppb coordinates as a bridging bidentate ligand to Cu(I) atoms. The crystal is monoclinic, space group P21/n, cell parameters: a = 10.310(2) A?; b = 18.730(4) A?, c = 17.630(4) A?, β = 95.10(3)°, Z = 4, V = 3391.0(12) A?3, R = 0.0603, Rw = 0.1434.
