Abstract: Bis(dichlorophosphino)aniline, PhN(PCl2)(2), reacts with stoichiometric amounts of 2,2 ' -thiobis(4,6-di-tert-butylphenol) to afford a 10-membered heterocycle, PhN(PCl)(2){(-OC6H2(' Bu)(2))(mu -S)((' Bu)(2)C6H2O-)} (1), in high yield. The structure of the heterocycle has been determined by a single-crystal X-ray analysis. The 10-membered heterocycle 1 reacts with SbF3 to afford the corresponding fluoro derivative 2 in good yield. The compounds 1 and 2 act as tridentate ligands with molybdenum carbonyl derivatives, forming complexes of the type [Mo(CO)(3)-{eta (3)-PhN(PX)(2){(-OC6H2(' Bu)(2))(mu -S)((' Bu)(2)C6H2O)}-kappaP,kappaP,kappaS}] (3 X = Cl, 4 X = F). A crystal structure of the fluoro derivative 4 showed the facial tricarbonyl complex comprising a relatively strain-free tetracyclic structure with molybdenum in an octahedral environment; the two phosphorus and the sulfur centers were the donor atoms. Compound 2 readily reacts with Ru(M), Pd(II), and Pt(H) derivatives to form chelate complexes, demonstrating the eta (2) mode of coordination.
