The reactions of (CO)5Mo(Ph2PCI) with KNSO or K2SN2 in acetonitrile produce (CO)5Mo(Ph2PNSO) (3a) or (CO)5MoP(Ph)2NSN(Ph)2PMo(CO)5 (4a), respectively. An X-ray crystal structure determination of 4a shows that the Ph2PNSNPPh2 ligand adopts a cis,trans conformation. A variable-temperature 31P NMR spectroscopic study of 4a provides evidence for a cis,trans → trans,cis interconversion (AG?213 = 9.4 ± 0.2 kcal mol-1) in solution.
