发明名称 Unsaturated accelerators for hydrosilation
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./!
