Department of Chemistry, Gobi Arts & Science College, Gobichettipalayam-638 456, Tamilnadu, India Department of Chemistry, Sri Ramakrishna Mission Vidyalaya College of Arts & Science, Coimbatore-641 020, Tamilnadu, India Manuscript received 16 April 2008, revised 25 August 2008, accepted 2 September 2008 Complexes of the type [RuCI(CO)(B)(L)] (B = PPh3, AsPh3, py or pip; L = monobasic tridentate Schiff base) have been synthesized by the reaction of equimolar amounts of [RuHCI(CO)(EPh3)2(B)] and Schiff bases in benzene. The resulting complexes have been characterized by analytical and spectral (IR, electronic, NMR) data. An octahedral structure has been assigned to all these complexes. The new complexes have been exhibit catalytic activity for the oxidation of benzyl alcohol and cyclohexanol in the presence of N-methylmorpholine-N-oxide as co-oxidant.
