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.
提供了一种制备丙烯氧基有机硅化合物的方法。该方法包括在催化剂(C)的存在下,反应(A)一个最初的有机硅化合物和(B)一个丙烯酸酯化合物。最初的有机硅化合物(A)具有一个醇官能团(即单羟基官能团)。催化剂(C)的化学式为M[RC(O)CHC(O)R]4,其中M是IV族过渡金属,每个R是独立选择的取代或未取代的烃基。还提供了通过该方法制备的丙烯氧基有机硅化合物。该丙烯氧基有机硅化合物在不依赖有毒催化剂的情况下提高了纯度。
