  1H, 31P and 195Pt NMR characterization, and X-ray molecular structures of five- and six-membered platinum(II) and palladium(II) metallacycles from the alcoholysis of di- and triazaphosphole complexes

  摘要：

  The 1,2,3-diazaphosphole <(P=C(H)C(Me)=NN) over bar>Me (L-A) and the 1,2,4,3-triazaphospholes <(P=NC(Ph)=NN) over bar>Me (L-B) and <(P=NN(Me)C(Me)=N) over bar> (L-C) form Pt(II) and Pd(II) complexes of stoichiometry MX2(PEt3)L (X=Cl, Br) whose controlled reactions with alcohols, generally methanol, have been studied by H-1, P-31 and Pt-95 NMR spectroscopy. Discrete intermediate species and the final novel monomeric phosphite metallacycles (sigma-P bonding of a {P(=O) (OR)R'}(-) function and N-coordination of either an imine or amine function) have been identified by their characteristic multinuclear NMR data. These data allow a stepwise mechanism for the azaphosphole ring-opening to be proposed. Two representative products of the series derived from L-B and L-C, namely [Pt{P(=O)(OMe)N(H)-C(Ph)=NN(H)Me}(Cl) (PEt3)] (19c) and [Pt{P(=O)(OMe)N(H)N(Me)C(Me)=NH}(Cl)(PEt3)] (20c) have been characterized by X-ray structure investigations. In the crystal the bonding of the P,N-chelating ligand in 19c is different to that identified in solution; the two ligand forms found can be described in terms of amidine tautomerism. (In this paper for simplicity we refer to a {P(=O) (OR)R'}(-) ligand as a phosphite; this is strictly only correct if R is (bonded through) an electronegative element and in cases where R is C-bound the ligand is more properly a phosphinate).
