Regiospesific addition of methyldichlorosilane to styrene

Influence of various Pt-containing catalytic systems and additives to them on regioselectivity of styrene hydrosilylation by methyldichlorosilane was studied. The regiospesific approach to methyl(2-phenylethyl)dichlorosilane in the presence of tetrakis(triphenylphosphine)platinum Pt(0) is developed.

SATURATED N-HETEROCYCLIC CARBENE-LIGAND METAL COMPLEX DERIVATIVES, PREPARING METHOD THEREOF, AND PREPARING METHOD OF SILANE COMPOUND BY HYDROSILYLATION REACTION USING THE SAME AS CATALYST

Provided are a saturated N-heterocyclic carbene-ligand metal complex derivative, a method for preparing the same, and a method for preparing a silane compound by hydrosilylation using the same as a catalyst. To describe in more detail, the metal complex derivative has a saturated N-heterocyclic carbene derivative and an olefin ligand at the same time. A silane compound is prepared by hydrosilylation in the presence of the metal complex derivative as a catalyst. The provided metal complex derivative of the present invention has superior stability during hydrosilylation reaction and is capable of effectively performing the hydrosilylation reaction at low temperature even with small quantity. Further, a product with superior regioselectivity may be obtained. In addition, after the hydrosilylation reaction is completed, the metal complex derivative may be recovered and recycled.

The first alkene-platinum-silyl complexes: Lifting the hydrosilation mechanism shroud with long-lived precatalytic intermediates and true Pt catalysts

The synthesis, characterization, and exploratory chemistry of two classes of alkene-platinumsilyl complexes, which have been postulated as hydrosilation intermediates, are described in this report. The unique dimeric complexes 1, [R3Si(u-Cl)(η2-COD)Pt]2 {R3Si = Et3Si, MeCl2Si, Me2ClSi, "(EtO)3Si", PhMe2Si, and (Me3SiO)Me2Si: COD = cycloocta-1,5-diene}, and the bis-silyl complexes 2, (η4-COD)Pt-(SiR3)2 (R3Si = Cl3Si, MeCl2Si, Me2ClSi, and PhMe2Si), are formed from the sequential reaction of 2 and 4 equiv of the corresponding hydrosilanes, respectively, with Pt(COD)Cl2 in the presence of a small excess of COD. Complexes 1 are stable for many days in solution at room temperature but decompose via slow elimination of chlorosilane. Some of the bis-silyl compounds 2 are stable for extended periods under inert atmosphere and especially below 0 °C, either in the solid state or in solution (in the presence of a small excess of free COD). Complexes 2 display catalytic activity as discrete, molecular, and mononuclear species for hydrosilation and isomerization reactions. Compound 2c (R3Si = MeCl2Si) MeCl2Si) was fully characterized via multinuclear NMR spectroscopy and x-ray crystal structure analysis. The facile H-transfer rather than Si-transfer to bound COD provides experimental support for the sequence of insertive steps in the Chalk-Harrod catalytic cycle, at least for Pt-catalyzed hydrosilation.
