title: Synthesis and structure studies of complexes of some second row transition metals with 1-(phenylacetyl and phenoxyacetyl)-4-phenyl-3-thiosemicarbazide.
abstract: The synthesis of the new complexes of 1-phenylacetyl-4-phenyl-3-thiosemicarbazide (H2papts) and 1-phenoxyacetyl-4-phenyl-3-thiosemicarbazide (H2Pxapts); [Ru(HL)2(H2O)2], [Rh(HL)3], [Ag(H2L)(H2O)2](NO3), trans-[UO2(HL)(bipy)(AcO)(H2O)2] (H2L = H2papts, H2pxapts; bipy = 2,2'-bipyridyl), [Ag(H2papts)(bipy)]+ and [Pd-(Hpapts)(bipy)]+ is described. Characterization of these complexes by IR, electronic and 1H-NMR spectra, conductometric titrations and thermal analysis is included. The complexes [Ru(HL)2(H2O)2] were found to be efficient catalysts for the oxidation of primary alcohols to aldehydes and acids, secondary alcohols to ketones and aryl halides to aldehydes and acids in the presence of NaIO4 as co-oxidant.
