Owing to their unique properties, molecules containing the difluoromethyl group (CF2H) are of great interest. Tributyl(difluoromethyl)stannane has now been used for the selective and efficient direct ipso difluoromethylation of aryl iodides, heterocyclic iodides, and β‐styryl halides (see scheme). The straightforward preparation of the difluoromethylating reagent makes this approach particularly valuable
由于其独特的性能,含二氟甲基(CF 2 H)的分子引起了人们的极大兴趣。三丁基(二氟甲基)锡烷现已用于芳基碘化物,杂环碘化物和β-苯乙烯基卤化物的选择性和高效直接ipso二氟甲基化反应(参见方案)。直接制备二氟甲基化试剂使该方法特别有价值。
