intramolecular aryldifluoromethylation of activated alkenes under mild reaction conditions has been developed. This reaction provides a new method for construction of a variety of difluoromethylated oxindoles. Mechanistic investigations indicate that a difluoromethyl radical, which was triggered by Pd(0), initiated the cascade sequence through an addition to the alkene.
在温和的反应条件下已开发出Pd(0)催化的活化烯烃分子内芳基二氟甲基化反应。该反应为构建各种二氟甲基化的吲哚提供了一种新的方法。机理研究表明,由Pd(0)触发的二氟甲基自由基通过加成烯烃而引发了级联序列。
