The synthesis and catalytic properties of molybdenum acetylide complexes CpMo(CO)3(-C≡CR), R = Ph(1), C6H4-p- CF3 (2) and C6H4-p-CH3 (3) has been studied. The molybdenum acetylide complexes were synthesized from CpMo(CO) 3Cl and aryl acetylenes via Stephens- Castro coupling reaction. These complexes were characterized by single crystal X-ray diffraction analysis, FTIR and 1H NMR spectroscopy. These complexes on treatment with hydrogen peroxide, formed corresponding molybdenum oxo-peroxo species. These in situ formed oxo-peroxo species were found very active (up to 100 % conversion) and selective (up to 100 %) oxidation catalysts for various refractory and nonrefractory sulfides. Interestingly, even though the molybdenum acetylide complexes are homogeneous, they could be recycled very efficiently by extracting the catalytically active molybdenum oxoperoxo species in aqueous phase.
