synthesis of pentafluoroethyl copper (CuC2F5) from a cupratereagent and ethyl pentafluoropropionate as one of the most economical and useful pentafluoroethyl sources was accomplished. The advantages of this method are; all the reagents employed are low-cost and operationally simple, and the CuC2F5 reagent is prepared in virtually quantitative yield. Furthermore, the CuC2F5 reagent prepared was successfully
由铜酸盐试剂和作为最经济和最有用的五氟乙基源之一的五氟丙酸乙酯直接合成了五氟乙基铜(CuC 2 F 5)。这种方法的优点是:所有使用的试剂都是低成本且操作简单的,并且CuC 2 F 5试剂的制备实际上是定量的。此外,制得的CuC 2 F 5试剂已成功应用于芳基硼酸和芳基溴化物的五氟乙基化反应的两种类型,从而以良好至优异的产率提供了五氟乙基化的芳族产品,包括大规模操作。
