Synthesis, characterization, and catalytic applications of Ru(III) complexes containing N-[di(alkyl/aryl)carbamothioyl]benzamide derivatives and triphenylphosphine/triphenylarsine

Six coordinated ruthenium(III) complexes of the type [RuX2(L)(PPh3)2] or [RuX2(L)(AsPh3)2] {where L = N-[di(alkyl/aryl)carbamothioyl]benzamide derivatives, X = Cl or Br} have been prepared by the reaction between [RuX3(PPh3)3] or [RuX3(AsPh3)3] (where X = Cl or Br) and N-[di(alkyl/aryl)carbamothioyl]benzamide derivatives in toluene and characterized by elemental analysis, spectral data (electronic, IR and EPR) and magnetic moment studies. The complexes act as efficient catalysts for the oxidation of alcohols in presence of N-methylmorpholine-N-oxide as oxidant at room temperature.

New Ru(III) complexes containing N-[di(alkyl/aryl)carbamothioyl]benzamide derivatives and PPh3/AsPh3 have been synthesized and characterized. These complexes exhibited good catalytic activity for oxidation of alcohols to carbonyl compounds in presence of NMO.Figure optionsDownload as PowerPoint slide
