摘要： Amphiphilic silicons which are dispersible or self-dispersing in water, have a high refractive index, and are prepared by a hydrosilylation reaction, resulting in products which are free of cyclic organopolysiloxanes. The high refractive index and dispersibility make the amphiphilic silicones useful in personal care and cosmetics where high shine or gloss is desired.

摘要： Internal dienes (including supported versions) and their Periodic Groups IX, X and Pt Group Metal Complexes as catalysts for hydrosilylation/coupling reactions. A process for the hydrosilylation of an unsaturated compound comprising reacting (a) a silyl or siloxy hydride with (b) an unsaturated compound in the presence of (c) one or more platinum complex containing said internal dienic ligand or (d) a platinum compound and one or more said internal dienic ligand additive. For Ru, Os, Co, Rh, Ir, Ni, or Pd, catalyzed processes such as C—C/C—N or C—O coupling comprising reacting (a) an aromatic halide/vinyl halide/an aromatic triflate with (b) a primary/secondary amine/amide, an alcohol/aryl boronic acid/aryl boronate/vinyl halide or an activated olefin in the presence of (c) a Group IX or X or Pt Group metal complex containing said dienic ligand(s) or (d) a suitable compound of these metals and of one or more said internal dienic ligand additive.

摘要： A hydrosilation process where a silicon hydride is reacted with an unsaturated reactant in the presence of a platinum catalyst and an accelerator selected from the group consisting of 1,7-octadiyne, 1,5-hexadiyne, cyclooctadiene, 5-vinyl-2-norbornene, 4-vinyl-1-cyclohexene, 2,5-bis(t-butylperoxy)-2,5-dimethylhexane, furan, 4H-Pyran-4-one, cis-4,7-dihydro-1,3-dioxepin, maleic anhydride, and dimethyldiallylmalonate. The accelerators are especially useful for facilitating the hydrosilation of unsaturated reactants where the unsaturation is in the internal portion of the reactant's structure, for example, as in cyclopentene and cyclohexene.
