Ph2P(O)C(S)N(H)R (R = Me, Ph) reacts with M(CO)3(η5-C5H5)Cl (M = Mo, W) in the presence of Et3N to give M(CO)2(η5-C5H5)(Ph2P(O)C(S)NR).The deprotonated ligand coordinates in a bidentate manner through N and S to give a four-membered ring system.M(CO)3(PPh3)2Cl2 (M = Mo, W) reacts with Ph2P(O)C(S)N(H)R (R = Me, Ph) in the presence of Et3N to give complexes in which the central metal atoms are seven coordinate through two ligands bonded via O and S to form five-membered ring systems, one PPh3, and two CO groups.The complexes were characterised by elemental analyse s, IR, 1H NMR, and 31P NMR spectroscopy, and an X-ray structural analysis of Mo(CO)2(PPh3)(Ph2P(O)C(S)NPh)2 * CH2Cl2.
