A process for the production of optically active Si compounds by reacting a meso-epoxide with a azidotrimethylsilane and a hydrocarbyl halide in the presence of a catalyst formed from the sequential treatment of hafnium t-butoxide or zirconium t-butoxide with one equivalent of homochiral optically active triisopropanolamine, water, and a source of trifluoroacetae ion is disclosed.
本发明揭示了一种通过在存在由依次处理得到的嘧啶丁醇铪或锆与一等量的同手性光学活性三异丙醇胺、水和三氟乙酸根离子源形成的催化剂的情况下,将中性环氧化物与偶氮三甲基硅烷和烃基卤化物反应,从而生产光学活性Si化合物的方法。
