Abstract
Ruthenium(II) complexes, [RuCl(L)(CO)(PPh3)2] {where L = N-[di(alkyl/aryl)carbamothioyl]benzamide derivatives}, are prepared from reaction between [RuHCl(CO)(PPh3)3] and N-[di(alkyl/aryl)carbamothioyl]benzamide derivatives in toluene and characterized by elemental analysis and spectral data (electronic, infrared, 1H NMR, and 31P NMR). The combination of [RuCl(L)(CO)(PPh3)2] (0.01 mmol) and N-methylmorpholine-N-oxide (NMO) (3 mmol) is an active catalyst for the oxidation of primary, secondary, cyclic, allylic, aliphatic, and benzylic alcohols to their corresponding aldehydes and ketones at room temperature. The oxidation protocol is simple to operate and gives the corresponding carbonyl compounds good to excellent yields.
