Hemilability and nonrigidity in metal complexes of bidentate P,P{double bond, long}S donor ligands

Hemilability and nonrigidity in a series of mixed P,P{double bond, long}S donor ligands has been studied in the complexes [Pd(P,P{double bond, long}S)Cl2], [Pd(η3-C3H5)(P,P{double bond, long}S)][SbF6], and [Rh(cod)(P,P{double bond, long}S)][SbF6] (P,P{double bond, long}S = Ph2P-Q-P(S)Ph2). The effect of bite angle, the rigidity of the ligand backbone, and the role of the ancillary ligands are discussed.

Polydentate Ligands Containing Phosphorus, III Synthesis and Nuclear Magnetic Resonance Studies of Some Unsymmetrical Potentially Tridentate Phosphine Chalcogenide Ligands

The synthesis via the useful lithium reagent intermediate, (C6H5)2P(S)CH2Li, is reported for eight compounds of the type 2CH, where R is methyl or phenyl and X is an electron pair, oxygen, or sulfur in various combinations.Two related compounds with three and four phosphorus atoms, respectively, per molecule have also been prepared from the same lithium reagent.Tris(diphenylthiophosphoryl)methane has three equivalent phosphorus atoms as indicated by the room temperature phosphorus-31 NMR spectrum, but at reduced temperature a favored conformation exists which has two equivalent phosphorus atoms and a unique one.Other phosphorus-31 and proton NMR data are reported. - Keywords: Polydentate Ligands, Phosphorus Chalcogenides, 31P NMR Spectra
