An efficient procedure to access to ortho-SCF3 substituted benzophenones from arynes and trifluoromethylthioesters has been developed under transition-metal free conditions. This difunctionalization process involves the first insertion of arynes into the C–S σ-bonds to achieve vicinal trifluoromethylthiolation-acylation of arenes in one step.

无过渡金属的三氟甲基硫醇化作用–通过插入C – S键来使芳烃酰化

在不含过渡金属的条件下，已经开发了从芳烃和三氟甲基硫代酯中获得邻-SCF3取代的二苯甲酮的有效方法。这种双官能化过程涉及将芳烃首先插入C-Sσ键中，以一步实现芳烃的邻位三氟甲基硫醇化-酰化反应。
