A visible-light induced three-component reaction of difluoroalkyl halides, unactivated alkenes, and alkynyl sulfones is described, providing a direct and general approach to the construction of synthetically valuable β-difluoroalkylated alkynes under room temperature conditions. This represents the first intermolecular alkynyl-difluoroalkylation of unactivated alkenes.
本文描述了一种可见光诱导的二氟烷基卤化物、非活化烯烃和炔基砜的三组分反应,为在室温条件下构建具有合成价值的β-二氟烷基化炔烃提供了一种直接而通用的方法。这代表了首例非活化烯烃的分子间炔基-二氟烷基化反应。
