In the presence of a catalytic amount of trityl hexafluoroantimonate, sequential reactions of epoxides with silylated nucleophiles, rearrangement of epoxides and C–C or C–O bond forming nucleophilic reaction onto the intermediate carbonyl compounds, proceed smoothly to afford the corresponding products in fairly good yields by one-pot procedure. Trityl hexafluoroantimonate (5 mol %) efficiently promotes
在催化量的六氟锑酸三苯甲基酯存在下,环氧化物与硅烷化亲核试剂的顺序反应、环氧化物的重排和 C-C 或 C-O 键在中间体羰基化合物上形成亲核反应,顺利进行,以相当好的方式提供相应的产物一锅法产量。六氟锑酸三苯甲基酯(5 mol%)有效地促进了上述多个连续反应。
