Abstract Treatment of the sulfur ylide complex (CO)5Cr[CH2S(O)Me2] (1) with the bifunctional phosphines Ph2PCH2ERn (ERn = SMe, SPh, SePh) lead to pentacarbonylchromium phosphorus ylide complexes (CO)5CrCH2PPh2CH2ERn. Only the S-methyl derivate could be converted to the metallocycle (CO)4[xxx] (ERn = SMe) by UV-irridiation. The ylide chelate complex (CO)4[xxx]Ph2 is formed directly by the thermal reaction of Ph2PCH2SbPh2 with 1. N o ylide complexes result from the reaction of 1 with (Ph2Sb)2CH2 and (MeS)2CH2. The only products identified were (CO)5Cr[Ph2SbCH2SbPh2] and [(CO)5CrS(Me) - ]2CH2, respectively.

Abstract A series of ionic phosphorus ylide complexes of gold(I) halides has been prepared and characterized through analytical and spectroscopic data. The compounds are of the type [R3PAu-CH2PR3]⊕Cl⊖, R = C2H5, and [(R3PCH2)2Au]⊕X⊖ where R = CH3, C2H5, n-C4H9, C6H5, and X = Cl, Br (1-6). Along with a cyclic complex [(C2H5)2P(CH2)2Au]2 (7) these materials have been tested in a pharmacological study for a possible use in an oral arthritis therapy.Compounds 1 and 5-7 showed no or only neglegible effects on Adjuvans-arthritis induced in rats, while 3 and 4 were very toxic. Complex 2 was comparable to standard chrysotherapeutic agent3 in a preliminary study, but a more detailed investigation including LD50 tests for mice showed too narrow a gap between its toxical and therapeutically useful doses.
