A variety of substrates containing hydroxy groups have been protected as their corresponding trimethylsilyl ethers using 1,1,1,3,3,3-hexamethyldisilazane in the presence of indium tribromide. The catalyst indium tribromide activates the 1,1,1,3,3,3-hexamethyldisilazane and accelerates the reaction under mild reaction conditions at room temperature.
多种含有羟基的底物已在三甲基硅醚的对应物中被保护,使用了在溴化铟存在下的1,1,1,3,3,3-己六甲基二硅氮。催化剂溴化铟激活了1,1,1,3,3,3-己六甲基二硅氮,并在室温的温和反应条件下加速反应。
