摘要
在1.0 mol%二(全氟辛基磺酸)二茂锆存在下,吲哚与醛、酮在室温、四氢呋喃中反应10~25 min,生成二吲哚甲烷衍生物,收率达86%~96%.催化剂二(全氟辛基磺酸)二茂锆能重复使用6次,转化率仍有90%;反应不需要在严格的无水条件下进行,上述过程为二吲哚甲烷衍生物制备提供一条新的有效途径.
In the presence of 1.0 mol% zirconocene bis(perfluorooctanesulfonate)s, indoles reacted with aldehyde/ketone at room temperature in tetrahydrofuran for 10~25 rain to give diindolylmethane derivatives in 86%~96% yields. The catalyst zirconocene bis(perfluorooctanesulfonate)s can be reused 6 times, and the conversion rate is still as high as 90%. This reaction does not require strict anhydrous conditions. This procedure provides a new and efficient way for preparing diindolylmethane derivatives.
