A new method for the preparation of aluminum and titanium trisphenoxides was realized using tetraallyltin or α-pinene as a proton-trapping agent. Thus obtained chlorotitanium reagent was converted to the corresponding cation-type reagent, which proved to be an effective catalyst for epoxide rearrangements.
使用四烯丙基锡或α-蒎烯作为质子俘获剂,实现了制备三苯氧基铝和钛的新方法。由此获得的氯化钛试剂转化为相应的阳离子型试剂,被证明是环氧化物重排的有效催化剂。
