    摘要:
    This report focuses on Cu(I) catalyzed cycloaddition reactions between organic azides and the platinum diacetylide complexes trans-(PR3)(2)Pt(C=CR')(2) (where PR3 = P(OEt)(3), PEt3, (PBu3)-Bu-n, PPhMe2, PPh3, and PBn3; and R' = H, Ph, and p-PhNO2). Pt(II)-Diacetylides supported by P(OEt)(3), PEt3, (PBu3)-Bu-n, and PPhMe2 react with benzyl azide to provide syn/anti isomers of double cycloaddition products. In contrast, Pt(II)-diacetylide complexes supported by PPh3 and PBn3 afford single cycloaddition products, exclusively. Steric congestion enforced by the larger phosphines PPh3 and PBn3 prevent the second cycloaddition. Ground state DFT computations provide some insight into the divergent reactivity and indicate that the pi-acidity of the phosphine ligands is a variable in the single vs double cycloaddition outcome.

  • Preparation of models and oligomers of metal alkynyls

    absence of palladium catalyst yields metal alkynyl oligomers. Comparison of 31P-NMR and gel permeation chromatography (GPC) analyses indicates that the GPC technique represents a reliable method to estimate polymer chain lengths for polymers bearing branched aromatic spacers, in spite of the rigid-rod shape of the polymer backbone. Single crystal X-ray determinations of model compounds demonstrate

  • Organometallic Oligomers Based on Bis(arylacetylide)bis(P-chirogenic phosphine)platinum(II) Complexes: Synthesis and Photonic Properties
    作者:Antony Lapprand、Naïma Khiri、Daniel Fortin、Sylvain Jugé、Pierre D. Harvey

    A series of P-chirogenic oligomers of the type (-CEC aryl-C C-PtL2-)(n) [L = (R)- and (S)-P(Ph)(iPr)(C17H35); aryl = 1,4-benzene, 2,1,3-benzothiadiazole] along the corresponding achiral analogues (L = PBu3) and model complexes PhC CPtL2C CPh were prepared from the ephedrine strategy and were fully characterized [H-1, P-31 NMR; IR; small-angle X-ray scattering (SAXS); gel permeation chromatography (GPC); thermal gravimetric analysis (TGA); circular dichroism, UV-vis, and luminescence spectroscopy; photophysics, and degree of anisotropy measurements]. From the CD measurements, the chiral environment of the phosphine ligands is modestly felt by the aryl moieties. Concurrently, the TGA shows that the P(C17H35)(Ph)(i-Pr)-containing materials are more stable than those containing the shorter chain ligand PBu3, and exhibits red-shifted absorption and emission bands compared to those including the PBu3 ligands. The presence of the long chain on the phosphorus atoms does not greatly alter the photophysical parameters, notably the emission lifetimes, and fast triplet energy transfer terminal* --> central unit has been deduced from the absence of luminescence arising from the terminal units.
