Dichlorodinickel(I) complexes with μ2-CO or μ2-CS bridges and trimethylphosphane ligands: Homologous composition, but different frameworks

High ligand mobility is shown by the coordinatively unsaturated nickel(I) compound 1 with a short Ni-Ni distance and an asymmetric CO bridge. The thio homologue 2 contains the novel (thiocarbonyl)trimethylphosphorane bridging ligand, which sits like a 'stork's nest' on top of the roof-shaped dinuclear complex. In contrast to 1, complex 2 does not show fluctional behavior and can be methylated without decomposition. X = Cl, Me.

Nickel-heterocumulene complexes stabilized by trimethylphosphine: Synthesis, characterization and catalytic application in organozinc coupling with CS2

The reactivity of Ni(PMe3)4 with CO2, CS2 and SCNPh was studied. Although CO2 is structurally homologous compound with CS2 and SCNPh, its reactivity with Ni(PMe3)4 shows a different result with those of CS 2 and SCNPh. Reactions of Ni(PMe3)4 with carbon disulfide and phenyl isothiocyanate in THF give the tetrahedral coordinate complexes (Me3P)3Ni(η2-CS2) (1) and (Me3P)3Ni(η2-SCNPh) (3), characterized by standard spectroscopic methods and X-ray diffraction. Nickel(0) complexes 1 and 3 are stabilized by the strong donor ligand PMe3. In the case of CO2, attempts to isolate the expected nickel(0) complex (Me 3P)3Ni(η2-CO2) (4) proved to be unsuccessful. To further extend the utility of our nickel catalysts, the catalytic coupling of organozinc bearing different functionalities with CS 2 was explored. With 10 mol% of 1 as the catalyst, MeZnMe, EtZnEt and PhZnBr coupled with CS2 to form the corresponding methyl dithiocarboxylate following esterfication of the initial products.

Synthesis and X-ray Structure of the Nickelabenzocyclopentene Complex . Reactivity Toward Simple, Unsaturated Molecules and the Crystal and Molecular Structure of the Cyclic Carboxylate

Facile cyclometalation to the nickelacyclopentene complex (1) occurs upon alkylation of NiCl2(PMe3)2 with 2 equiv of Mg(CH2CMe2Ph)Cl, in the presence of traces I(1-).Compound 1 has been fully characterized by spectroscopic and X-ray studies.Its
