[en] Decarbonylation reactions of M(CO)6 and M(MeCN)3(CO)3 (M=Mo, W) with tris-(tri-phenylphosphine)chlororhodium (1) in acetonitrile are studied. At 80 deg initial rhodium complex, interacting with M(CO)6, quantitatively transforms into Rh(PPh3)2COCl in 5 (Mo) and 10(W) min. Reactions proceed by means of sequential transfer of carbonyl groups on rhodium: coordination vacancies formed are filled with MeCN and PPh3 molecules. Complexes containing PPh3 are not practically subjected to further decarbonylation. Among M(CO)6 decarbonylation products cis-tetracarbonyl, cis-dicarbonyl complexes are present, i.e. reactions of carbonyl group splitting off are stereospecific. Decarbonylation of Mo(MeCN)3(CO)3 results in the formation of Mo(PPh3)2(MeCN)2x(CO)2
