Synthesis, Characterisation and Oxidative Addition Products of Palladium (0) Complexes Ligated by Heterocyclic Thioamide

R. N. Pandey, Sheo Shankar Kumar and A. K. Nag

The phosphine complexes of palladium (0) with heterocyclic thioamide, 2-mercapto-3-benzylquinazoline- 4-one have been isolated and characterised on the basis of elemental analyses, molar conductance, magnetic moment and spectral studies. Oxidative addition products with inorganic acids have also been reported. The coordination of thioamide ligand occurs through sulphur and square planar configuration to Pd (II) and tetrahedral geometry to Pd (0) complexes are assigned.
