  The reactions of MXCl(PPh3)3 (M = Ru, Os; X = H, Cl) with (C6H3-2,6-Trip2)GeCl (Trip = 2,4,6-iPr3C6H2) have been investigated. Teatment of MXCl(PPh3)3 with (C6H3-2,6-Trip2)GeCl led to the formation of the dichlorogermyl chloro- or hydrido- ruhenium/osmium complexes (PPh3)XMGeCl2(C6H3-2-η6-Trip}-6-Trip) (M = Ru, X = Cl, 1; M = Os, X = Cl, 2; M = Ru, X = H, 3; M = Os, X = H, 4) via insertion of the germylene

  An improved synthesis of [(p-Cym)OsCl2]2 (1) using OsCl3·3H2O as the starting material is described. 1 reacts with PMe3, PPH3 and CO by Cl bridge cleavage to give (p-Cym)OsCl2(L) (2–4). Replacement of the chloride ligands in 1 and 2 (L = PMe3) by iodide leads to the formation of [(p-Cym)OsI2]2 (5) and (p-Cym)OsI2(PMe2 (6), respectively. Both 2 and 6 react with NaBH4 to give the dihydrido complex (p-Cym)OsH2(PMe3)

  The enthalpies of reaction of [OsCl2(p-cymene)](2) (1) (p-cymene = eta(6)-CH3C6H4CH(CH3)(2)) with a series of monodentate phosphines (PR3), leading to the formation of OsCl2(p-cymene)(PR3) complexes, have been measured by anaerobic calorimetry in CH2Cl2 at 30 degrees C. These reactions are rapid and quantitative. The overall relative order of stability established is as follows: PPh(NC4H4)(2) < P(NC4H4)(3) < P(p-CF3C6H4)(3) < PPh2(NC4H4) < PPh3 < P(p-ClC6H4)(3) < P(p-CH3C6H4)(3) < P(p-FC6H4)(3) < PCy3 < PBz(3) < (PPr3)-Pr-i < P(p-CH3OC6H4)(3) < P(NC4H8)(3) < PPh2Me < PPhMe2 < PEt3 < PMe3. A quantitative analysis of ligand effects for the present data helps clarify the exact steric versus electronic ligand contributions to the enthalpy of reaction in this system. Both steric and electronic factors appear to play an important role in dictating the magnitude of the enthalpy of reaction. The data are compared to the previously studied RuCl2(p-cymene)(PR3) system.

  Reactions of the platinum-group metal halide complexes [PtCl2(COD)] (COD = 1,5-cyclo-octadiene), [Cp*RhCl2(PPh3)] (Cp* = eta(5)-C5Me5), [Cp*IrCl2(PPh3)], [(p-cymene)RuCl2(PPh3)] and [(p-cymene)OsCl2(PPh3)] with symmetrically trisubstituted (acetyl or phenyl) guanidines, mediated by silver(I) oxide, give complexes formally containing the triazatrimethylenemethane ligand. A full X-ray crystal structure determination is reported for the N,N',N "-triphenylguanidine dianion complex [PtNPhC(=NPh)NPh}(COD)] 4a which shows the presence of a planar Pt-NR-C(=NR)-NR four-membered platinacycle. At room temperature (r.t.), the H-1- and C-13H-1}-NMR spectra of 4a yield a single set of COD CH and CH2 resonances. At 240 K however, two sets of resonances are observed, interpreted in terms of fluxionality of the C=N-Ph moiety. Attempted synthesis of the analogous platinum triacetylguanidine complex yields the new ureylene complex [PtNAcC(=O)NAc}(COD)], via a hydrolysis reaction. Starting with the osmium compound, both the guanidine complex [(p-cymene)OsNAcC(=NAc)NAc}(PPh3)] 9 and the ureylene complex [(p-cymene)OsNAcC(=O)NAc}(PPh3)] 10 were formed; similar results were obtained for the iridium system.
