A method for preparing (trichloromethyl)organosilanes by the catalytic decarboxylation of the corresponding trichloroacetoxysilanes RMe2SiOC(O)CCl3 (R = Me, ClCH2, Ph, Me3Si, and H) has been developed. The method involves heating the starting compounds without a solvent in the presence of a catalyst (quaternary ammonium salts or potassium salts with the addition of crown ethers). Tertiary amines (Et3N
已经开发了一种通过相应的三氯乙酰氧基硅烷 RMe2SiOC(O)CCl3(R = Me、ClCH2、Ph、Me3Si 和 H)的催化脱羧来制备(三氯甲基)有机硅烷的方法。该方法包括在催化剂(季铵盐或钾盐与冠醚的加入)存在下在没有溶剂的情况下加热起始化合物。只有在供体非质子溶剂(THF、乙腈)中在氧气存在下进行加热时,叔胺(Et3N、Bu3N)才能催化该反应。(三氯乙酰氧基)有机硅烷的热分解与催化脱羧相反,在较高温度下开始并产生产物混合物。
