Abstract
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.
