Abstract: The dimeric complex, [(OC)2Rh(μ-Cl)2 Rh(CO)2], undergoes bridge splitting reaction with Ph2PCH2CH2SEt (P-S) to produce the chelated complex, [Rh(CO)Cl(PS)](1) (PS =η2 - coordinated P-S ), which on oxidative addition with MeI and I2 yields [Rh(COMe)ICl(P S)](2) and [Rh(CO)I2Cl()](3) respectively. On the other hand , the bridge splitting reaction of the dimeric complex, [(COD)Rh(μ-Cl)2 Rh(COD)] (COD =1,5- cyclooctadiene), with P-S produces a non-chelated complex, [Rh(COD)Cl(P~S)](4) (P-S =η1-coordinated P-S). All the complexes have been characterized by elemental analyses, IR, 1 H and 31P{1H} NMR spectroscopy. The catalytic activity of the complexes 1 and 4 for carbonylation of methanol is found to be higher than that of the well known species, [Rh(CO)2I2].
