摘要

我们已经开发了一种直接的方法来合成远端含杂芳基的二氟甲基取代酮。该方法利用双（二氟乙酰基）过氧化物（由DFAA和尿素·H₂O₂原位生成）作为二氟甲基化剂，通过远端异芳基迁移实现非活化烯烃的二氟甲基异芳基化。事实证明，阳光促进了这种转变。

Difluoromethylheteroarylation of unactivated alkenes through remote heteroaryl migration with bis(difluoroacetyl) peroxide

We have developed a straightforward method for synthesizing distal difluoromethyl-substituted ketones bearing heteroaryl groups. This approach utilizes difluoromethylheteroarylation of unactivated alkenes through remote heteroaryl migration by employing bis(difluoroacetyl) peroxide (generated in situ from DFAA and urea·H₂O₂) as the difluoromethylating agent. Sunlight was proved to promote this transformation.
