The thioxophosphanes RPS (a - f) a), C2H5 (b), C6H5 (c), 4-CH3OC6H4 (d), 4-CH3C6H4 (e), 4-FC6H4 (f)> are stabilized in the protecting coordination sphere of the carbonylmolybdenum and -manganese complexes η2(CO)2RPS>CO (4a - d), 5a, c - f) ( = η5-C5H5Mo(CO) (4), Mn(CO)3 (5)). 4a - d, 5a, c - f are obtained by dehalogenation of the thioxophosphoranes RP(S)Cl2 (1a - d) with Na5-C5H5Mo(CO)3> (2) and activated magnesium in the presence of Mn2(CO)10 (3), respectively, or alternatively with Mg2 in THF.As by-products also the dithioxophosphorane complexes (CO)2RPS2CO (6d, 7c - f) ( = η5-C5H5Mo( CO) (6), Mn(CO)3 (7)) are formed by sulfur transfer reactions.For the generation of 4, 6 electronic reasons are relevant.Considering the formation of the manganese compounds 5, 7 a distinct dependence of the product distribution is observed on the steric demand of the organic substituents R. 6d crystallizes in the triclinic space group P1/ with Z = 2.
