摘要 在无溶剂条件下,硅胶吸附的水合三氯化铈-碘化钠(CeCl3·7H2O-NaI)可以作为路易斯(Lewis)酸有效催化活泼亚甲基化合物和烯丙醇的直接烷基化反应,得到较高产率的烷基化产物(62%~90%).该催化剂经过简单处理至少可以循环利用四次,第四次循环后产率达到78%. Alkylation of 1,3-dicarbonyl compounds with allylic alcohols was performed smoothly in good yields (62%~90%) under solvent-free conditions with SiO2-supportted CeCl3·7H2O-NaI as a highly efficient and recyclable catalyst.This catalyst system could be easily recovered and then reused in the alkylation at least four times without significant loss of catalytic activity.
