Thiocarbamoylphosphine sulfides 1a-c and oxides 2a-c are ambidentate chelating ligands which may form monomeric or dimeric complexes with carbonylmetal halides.The reaction of 1a-c with ClMn(CO)5 and ClRe(CO)5 yields the monomeric cis-tetracarbonyl complexes 3a-c and 4a-c with S,S'-coordination.The phosphine oxides 2a-c first form tetracarbonyl complexes which dimerize spontaneously under loss of CO to give the anti-fac-tricarbonyl complexes 5a-c and 6a with bridging three-coordinate sulfur.On refluxing in n-hexane solution, 3a-c and 4b,c are converted into the corresponding dimers 7a-c and 8b,c.Dissolving of 7b, c in CH2Cl2 leads to re-formation of 3b, c, the free ligands 1b, c and inorganic manganese compounds. - Keywords: Chelate Ligands, Thiocarbamoylphosphine Sulfide, Thiocarbamoylphosphine Oxide, Manganese Complexes, Rhenium Complexes
