	abstract = {Oxidative addition of H2S to MoRu(CO)(6)(mu-dppm)(2) (1) at similar to 20 degrees C in toluene yields an isolable complex formulated as Mo(CO)(3)(mu-SH)(mu-CO)(mu-dppm)(2)RuH(CO) (2) via the possible intermediate Mo(CO)(3)(mu-H)(mu-CO)(mu-dppm)(2)Ru(SH)(CO) (4) (dppm = Ph2PCH2PPh2) that is detectable at lower temperatures. Over 2 days, species 2 in toluene loses H-2 (and CO) to yield the bridged-sulfide product, Mo(CO)(2)(mu-CO)(mu-S)(mu-dppm)(2)Ru(CO) (5) that is also formed directly from the reaction of 1 with elemental sulfur. The solid-state molecular structure of 5 is determined by X-ray crystallography. A further hydrido-sulfhydryl species, possibly Mo(CO)(3)(mu-SH)(mu-H)(mu-dppm)(2)Ru(CO)(2) (3), is in equilibrium with 2 at ambient temperature.},

Variable-temperature H-1 NMR spectra of the Pd-2(1) complexes Pd2X2(dMPM)(2) (X = Cl, Br, or I; the P-P ligands in the Pd-2 complexes are always bridged, but for convenience, the mu-symbol is omitted) show the complexes to be fluxional in solution, the barriers to a ring-flipping process being DeltaGdouble dagger = 37.9, 39.0, and 43.2 +/- 0.9 kJ mol(-1) for the chloro, bromo, and iodo complexes, respectively. Treatment of Pd2X2(P-P)(2) (X = Cl or Br) with X-2 generates the stable, face-to-face Pd-2(II) derivatives trans-Pd2X4(P-P)(2), while oxidation of Pd2I2(P-P)(2) complexes with I-2 generates a new type of symmetrically di-iodo-bridged, five-coordinate complexes Pd2I2(mu-I)(2)(dmpm)(2) and Pd2I2(mu-I)(2)(depm)(2). The molecular crystal structures of four dipalladium(II) complexes are described: trans-Pd2Cl4(dmpm)(2).2CHCl(3), trans-Pd2Br4(dmpm)(2), trans-Pd2Cl4(depm)(2), and Pd2I2(mu-I)(2)(dmpm)(2). Solution NMR and UV-vis absorption spectra are consistent with the solid-state structures determined by X-ray diffraction. The stability of the dimeric Pd(II) complexes is attributed primarily to ligand steric factors.},

	abstract = {Solution kinetic and mechanistic studies were performed on the abstraction of sulfur from Pd(2)X(2)(mu-S)(mu-dpm)(2) [X = Cl (2a), Br (2b), I(2c)] using bis(diphenylphosphino)methane (dpm) to give, respectively, Pd(2)X(2)(dpm)(2) [X = Cl (1a), Br (1b), I (1c)] and dpm(S). The reaction is first-order in both 2 and dpm with the reactivity trend in CHCl3 being X = Cl > Br > I. The activation parameters for the chloride system are Delta H-double dagger = 41 +/- 3 kJ mol(-1) and Delta S-double dagger = -127 +/- 10 J K-1 mol(-1), and for the bromide, Delta H-double dagger = 38 +/- 1 kJ mol(-1) and Delta S-double dagger = -144 +/- 4 J K-1 mol(-1), showing the entropy term is dominant in governing reactivity. Low-temperature NMR studies did not reveal the presence of observable intermediates. 2b and 1b undergo rapid diphosphine ligand exchange with dpm-d(2); with 2b, prior to any S-abstraction, Pd2Br2(mu-S)(dpm)(dpm-d(2)) (7b) and Pd2Br2(mu-S)(dpm-d(2))(2) (8b) are present, while Pd2Br2(dpm)(dpm-d(2)) (3b) and Pd2Br2(dpm-d(2))(2) (4b) are formed, as well as 1b and dpm(S)-d(2), in the abstraction reaction of 2b with dpm-d(2). The distribution of products is close to statistical on the basis of the stoichiometries of the reactants. Reaction of 2b with 1,1{\textquoteright}-bis(diphenylphosphino)ethane (dpmMe) proceeds in an analogous way generating 1b, Pd2Br2(dpm)(dpmMe) (5b), Pd2Br2(dpmMe)(2) (6b), dpm(S), and dpmMe(S). In contrast, 1b undergoes slow diphosphine ligand exchange with dpmMe to form 5b and 6b; 2b undergoes no ligand exchange with dpmMe prior to the S-abstraction reaction. The findings are rationalized in terms of postulated intermediates and transition states that include formulations with three equivalent diphosphines. No sulfur abstraction occurs on treating 2b with PPh(3), PPh(2)Me, or Ph(2)P(CH2)(3)PPh(2).},
