Abstract

The oxidative addition reactions of diphosphazane monosulfides, Ph2PN(R)P(S)Ph-2 (R = (S)-*CHMePh (1), CHMe2 (2)) with [Ru-3(CO)(12)] afford sulfur-monocapped triruthenium clusters of the type [Ru-3(mu-CO)(CO (7)(mu(3)-S){Ph2PN(R)PPh2-kappa(2)P,P}] (R = (S)-*CHMePh (3), CHMe2 (4)); the X-ray crystal structure of 3 reveals the chelating mode of coordination of the diphosphazane ligand, which is rarely observed for such type of complexes. The bridge-splitting reactions of 1 and 2 with [{Rh(mu-Cl)(CO)(2)}(2)] yield [Rh(CO)Cl{Ph2PN(R)P(S)Ph 2-kappa(2)P,S}] (R = (S)-*CHMePh (5), CHMe2 (6)); the X-ray crystal structure of 5 confirms that the 'CO' ligand is trans to the P=S bond. The reactions of [MCl2(COD)] with I and 2 yield chelate complexes, [MCl2{Ph2PN(R)P(S)Ph 2-kappa(2)P,S}] [M = Pd (7 and 8) or Pt (9 and 10)].
