  Synthesis, Characterization and Thermal Studies of Bipyridine Metal Complexes Containing Different Substituted Dithiocarbamates

  摘要：

  Complexes of the type [Mpy(2)(dedtc)(2)], and [Mpy(2)(dpdtc)(2)], where M = Mn(II), Fe(II), Co(II), Ni( II), Cu(II), Zn(II), py = pyridine, dedtc = diethyldithiocarbamate and dpdtc = diphenyl-dithiocarbamate, have been synthesized and characterized by elemental analyses, magnetic susceptibility, TGA/DSC and IR in the solid-state, and electronic spectroscopy and conductivity measurement studies in solution. The dithiocarbamato moiety has been found to be symmetrically bonded to the metal. The complexes are proposed to have a distorted-octahedral structure. The ligand field parameters 10 Dq, B and beta have also been evaluated. The value of b indicates a considerable orbital overlap in the complexes. A two-stage decomposition pattern leading to the formation of respective metal sulfide as the end-product has been observed in all the complexes. Their molar conductance indicated them to be non-electrolyte in nitrobenzene.

  Transition metal complexes (Mn --> Zn) of the dipyrromethane ligand, 1,9-dimesityl-5,5-dimethyldipyrromethane (dpm), have been prepared. Arylation of the dpm ligand alpha to the pyrrolic nitrogen donors limits the accessibility of the pyrrole pi-electrons for transition metal coordination, instead forcing eta(1),eta(1) coordination to the divalent metal series as revealed by X-ray diffraction studies. Structural

  affords bidentate ligands 2-(1H-pyrrol-2-yl)pyridine (PyrPyrrH) and 2-methyl-6-(1H-pyrrol-2-yl)pyridine (PyrMePyrrH). Metalation of these ligands in THF affords six-coordinate complexes Fe(PyrPyrr)2(THF)2 and Fe(PyrMePyrr)2(THF)2. Dissociation of labile solvent ligands provides access to four-coordinate Fe(II) complexes. Ligand disproportionation at Fe(PyrPyrr)2 results in the formation of Fe(PyrPyrr)3 and

  The application of a variety of iron complexes with chelating amine ligands as pre-catalysts in the representative cross-coupling of 4-tolylmagnesium bromide with cyclohexyl bromide was investigated. The results from this study indicate the performance of the pre-catalyst is inversely proportional to the strength of the chelate or macrocyclic effect of the amine ligand, as determined by the propensity
