Yield:18536-91-9 94.1%
Reaction Conditions:
Stage #1:1-dodecene with fumed silica-supported nitrogenous platinum complex at 110; for 0.5 h;
Stage #2:Triethoxysilane at 110; for 2.5 h;regioselective reaction;
Steps:
2.3. Hydrosilylation of olefins with triethoxysilane
Reactions were carried out in a three-necked flask with a magnetic stirrer and a reflux condenser with an attached drying system on the upper condenser. Olefin and platinum catalyst were stirred at the reaction temperature for 30 min before triethoxysilane which was added at a constant speed. The reaction mixture was heated at the reaction temperature within the stipulated time and then catalyst was separated from the raw product by decantation. After the removal of the raw product, a new portion of substrates was added and the reaction was repeated under the same conditions. Gas chromatography was employed to follow the course of the reaction by the appearance of product. All hydrosilylation products were characterized by 1H NMR and 13C NMR.
