    • Disclosed herein are a silane coupling agent and a method of preparing the same useful for a composite organic-inorganic material. The silane coupling agent is represented by the formula of R1R2R3Si—X, wherein R1, R2, and R3, respectively, represent straight or branched alkyl having 4 to 22 carbon atoms, alkoxy, phenyl, phenyl alkoxy, benzyloxy or phenyl alkyl group. The method comprises the steps of: dissolving a vinyl derivative in a solvent under a nitrogen or argon atmosphere; and reacting the resulting solution with an alkoxysilane derivative at a temperature of 20 to 200° C. for 1 to 72 hours in the presence of a metal catalyst. Alternatively, the method comprises the steps of: dissolving alkylmagnesium halide in a solvent under a nitrogen or argon; and reacting the resulting solution with haloalkoxysilane at a temperature of −78° C. to 50° C. for 0.1 to 5 hours.
    • 本文公开了一种硅烷偶联剂及其制备方法,可用于复合有机 - 无机材料。 硅烷偶联剂由式R 1 R 2 R 3 Si-X表示,其中R 1,R 2和R 3分别表示具有4至22个碳原子的直链或支链烷基,烷氧基,苯基,苯基烷氧基,苄氧基或苯基烷基。 该方法包括以下步骤:在氮气或氩气氛下将乙烯基衍生物溶解在溶剂中; 并使所得溶液与烷氧基硅烷衍生物在20〜200℃的温度下在金属催化剂存在下反应1〜72小时。 或者,该方法包括以下步骤:在氮气或氩气下将烷基卤化镁溶解在溶剂中; 并将所得溶液与卤代烷氧基硅烷在-78℃至50℃的温度下反应0.1至5小时。
