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 (tBu)2)μ-S) ((tBu)2C6H2O-)}(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-{η3-PhN(PX)2 {(-OC6H2(tBu)2) (μ-S) ((tBu)2 C6H2O-)}-κP,κP,κS}] (3 X = Cl, 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(II), Pd(II), and Pt(II) derivatives to form chelate complexes, demonstrating the η2 mode of coordination.
