A simple method for the introduction of a methyl and higher aliphatic group to various heteroarenes using very inexpensive reagents is described. It is based on the radical addition of a carboxylic xanthate followed by decarboxylation. Depending on the heteroarene structure, the decarboxylation can be spontaneous or induced by heating in N,N-dimethylacetamide or N-methyl pyrrolidone in a microwave
描述了一种使用非常便宜的试剂将甲基和高级脂肪族基团引入各种杂芳烃的简单方法。它基于羧酸黄原酸酯的自由基加成,然后进行脱羧。取决于杂芳烃结构,脱羧可以是自发的,或者可以通过在微波炉中的N,N-二甲基乙酰胺或N-甲基吡咯烷酮中加热来引发。
