摘要：

The new complexes [Os(III)Cl2(PPh3)2SQ'] (SQ' = o-semiquinone; 1,2-benzosemiquinone (SQ), 4-methyl-1,2-benzosemiquinone, 3,5-di(tert-butyl)-1,2-benzosemiquinone, tetrachloro(tetrabromo)-1,2-benzosemiquinone and 2,3-naphthosemiquinone) have been isolated. They were characterised by spectroscopic techniques and investigated by cyclic voltammetry. The complex [OsCl2(PPh3)2SQ] was found to be more efficient than the reported [Os(III)Cl2(PPh3)2acac] as a catalyst for the oxidation of primary alcohols to aldehydes and of secondary alcohols to ketones in the presence of N-methylmorpholine-N-oxide as co-oxidant.
