Organometallic Reactions Involving Hydro-Nickel, -Palladium, and -Platinum Complexes

摘要: Publisher Summary This chapter discusses the involvement of hydro complexes in reactions, such as isomerization, oligomerization, hydrosilylation, and hydrogenation unsaturated hydrocarbons. Hydro transition metals have been known for many years. A hydronickel intermediate was postulated nickel-catalyzed hydroalumination alkynes where small amounts Ni(acac)2 were found to accelerate rate cis-hydroalumination. Reduction with Hydrazine method is significant since it first one used preparation PtHCl(PEt3)2 from PtCl2(PEt3)2. Protonation triphenylphosphine, a variety acids has shown give hydroplatinum complexes. convenient route broad range hydrosilyl platinum reaction silyl Pt(C2H4)(PPh3)2 absence solvent. The oxidative addition H2 low-valent d8 complexes, IrCl(CO)(PPh3)2, common synthetic dihydro this triad prepared by hydrogenolysis σ-bonded ligands. thermolysis PtC1(COC8H17)(PPh3)2 gives PtHCl(PPh3)2 octene. chloroplatinic acid-catalyzed SiC13H heptene-3 prepare n-heptyltrichlorosilane good yield. In presence acid, methylphenylsilane reacts propylamine yield either mono- or disubstituted silane depending on ratio reactants.
