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)(H2O2)] (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 sectra, 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.
