Abstract
The reactions of chiral diphosphazanes. Ph2PN((S)-*CHMePh)PPhY (Y =Ph, N2C3HMe2-3,5) with [CpRu (PPh3)2Cl] and those of the monosulfides, Ph2PN(R)P(S)Ph2 (R = (S)-*CHMePh or CHMe2) with Ru3(CO)12. [RhCl(cod)]2 and [RhCI(CO)2]2 have been investigated. Molybdenum-palladium heterometallic complexes of the diphosphazanes, MeN(P(OR)2)2 (R = CH2CF3 or Ph) have been synthesised. Some unusual complexes have been obtained by the reductive carbonylation of cobalt and ruthenium halides in the presence of diphosphazanes, RN(PX2)2 (R = Me, X = OCH2CS or OPh; R = CHMe2, X = Ph). The structures of the products have been elucidated by NMR spectoscopy and in some cases confirmed by X-ray crystallography (e.g., 1–4).
