METHOD OF PREPARING ACRYLOXY-FUNCTIONAL ORGANOSILICON COMPOUNDS
A method of preparing an acryloxy-functional organosilicon compound is provided. The method comprises reacting (A) an initial organosilicon compound and (B) an acrylate compound in the presence of (C) a catalyst. The initial organosilicon compound (A) has one alcohol functional group (i.e., is monohydroxyl functional). The catalyst (C) has the formula M[RC(O)CHC(O)R]4, where M is a group IV transition metal and each R is an independently selected substituted or unsubstituted hydrocarbyl group. An acryloxy- functional organosilicon compound prepared by the method is also provided. The acryloxy-functional organosilicon compound is prepared in increased purity, without relying on toxic catalysts.

User-Friendly Platinum Catalysts for the Highly Stereoselective Hydrosilylation of Alkynes and Alkenes
With a view to addressing the shortcomings of traditional catalysts, a new generation of outstanding N- heterocyclic carbene platinum(0) complexes for the hydrosilylation of unsaturated carbon-carbon bonds is reported. Their discovery and application to the stereoselective addition of various silanes to silylated alkynes, terminal acetylenes, and olefins is presented. Insights into the catalytic cycle and the origin of the stereoselectivity are also discussed.
