    Characterization and structure of OsH(OH)(CO)(PtBu2Me)2
    摘要:
    A synthesis of the title compound by hydrolysis of OsH(C6H5)(CO)((PBu2Me)-Bu-t)(2) has the advantage that the product shows H-1 NMR spectra free of the influence of hydrogen bonding to water impurity. In the solid stale, the hydroxyl group interacts weakly with that of a neighbor. The Os-OH bond is rapidly split by H-2, to give H2O and Os(H)(2)(H-2)(CO)((PBu2Me)-Bu-t)(2).

    and the ability of the strongly π-acidic vinyl fluoride to rapidly trigger reductive elimination of benzene. The products of reaction of RuH(Ar)(CO)L2 with vinyl fluoride are redirected more towards ethylene formation when Ar carries fluorine substituents. The reaction products of OsH(R)(CO)L2 with vinyl fluoride revert to R-H elimination when R is methyl. Finally, the more π-acidic H2C CF2 triggers
    摘要MH(Ph)(CO)L2(L = PtBu2Me; M = Ru和Os)均与乙烯反应形成MF键。但是,Ru消除了苯,而Os消除了乙烯。相反,Ru(H)2(CO)L2和Os(H)2(CO)(1-丁烯L2均与乙烯反应生成乙烯MHF(CO)L2。两个氢化物产生的乙烯均归因于β-F从MCH2CH2F瞬态向M迁移,而RuH(Ph)(CO)L2的独特行为(给出了CF氧化加成产物Ru(η1-乙烯基)F(CO )L2)归因于难以获得RuIV,以及强π-酸性乙烯迅速引发苯的还原消除的能力。当Ar带有取代基时,RuH(Ar)(CO)L2乙烯的反应产物更倾向于乙烯形成。当R为甲基时,OsH(R)(CO)L2乙烯的反应产物恢复为RH消除。最后,酸性更强的H2C CF2触发了OsH(CH3)(CO)L2CH4的快速清除。第二个CF键的断裂产生亚乙烯基OsF2(CCH2)(CO)L2。通过加

    The reactions of OsH(Ph)(CO)L-2 (L = P'Bu2Me) with HSiMe3, H2SiPh3 or H3SiPh produce benzene and OsH3(silyl)(CO)L-2, which is characterized as a fac-H3OsP3 shape capped on the H-3 face by the silyl group. For H2SiPh2 and H3SiPh, these reactions are shown proceed through an intermediate Os(H)(2)(silylene)(CO)L-2 species. OsHF(CO)L-2 reacts with these silanes to give the same OsH3 product (and silyl-F). These reactions can be combined to effect osmium catalysis of conversion of Si-H + H2C=CHF to fluorosilane and H2C=CH2 from OsH3(SiMe3)(CO)L-2, or from the catalyst precursor OsHF(CO)L-2.
