hectorite and FeOx-pillared taeniolite) were synthesized by the intercalation of FeCl3 into clay interlayers and calcination. The synthesized catalysts were exploited for conversion of epoxides furnishing acetonides in good to quantitative yields with short time under mild conditions. The catalysts could be recovered and reused up to five times without appreciable loss of activity.
通过将FeCl 3嵌入粘土层中并进行煅烧,合成了FeO x桩状粘土(FeO x桩状膨润土,FeO x桩状
锂蒙脱石和FeO x桩状
钙钛矿)。将合成的催化剂用于在温和条件下短时间内以良好的定量收率转化提供
丙酮化物的
环氧化物。催化剂可以回收并重复使用多达五次,而不会明显损失活性。
