  Studies of new volatile copper(I) complexes with triphenylphosphite and perfluorinated carboxylates

  摘要：

  Copper(I) complexes with triphenylphosphite and aliphatic perfluorinated carboxylates of the type [Cu(mu-RCOO){P(OC6H5)(3)}](2), where R=CF3, C2F5, C3F7, C6F13, C7F15, C8F17 and C9F19 have been prepared as viscous liquids and characterised by C-13, F-19, P-31, Cu-63 NMR, IR and mass spectra. In the liquid state, a dimeric structure with Cu in trigonal symmetry linked by the bridging carboxylates is proposed. Temperature-dependent P-31 and Cu-63 NMR spectra were determined, in the 333-233 K range and single lines from both nuclei were detected, suggesting the fast exchange of triphenylphosphite in acetonitrile solution. Copper relaxation is sufficiently slow to record the signal, which is the first time that this has been reported for complexes with P(OC6H5)(3). Examination of C-13 and F-19 resonances confirm coordination of carboxylates in solution where few dimeric species with a geometry lower than T-d symmetry can exist. Thermal decomposition of complexes proceeds as a multistage process, yielding a mixture of Cu, Cu2O and Cu2P2O7. (C) 1999 Elsevier Science Ltd. All rights reserved.
