We report a simple protocol for (ethoxycarbonyl)difluoromethylthiolation of nucleophilic compounds using a difluoroalkyl sulfonium salt which can be prepared in situ via Tf2O-triggered electrophilic activation of a benzyl difluoroalkyl sulfoxide. With the protocol, difluoroalkylthiolated arenes, heteroarenes, α-difluoroalkylthiolated carbonyl compounds, etc. were obtained smoothly with good to excellent
我们报告了一种使用二氟烷基锍盐对亲核化合物进行(乙氧基羰基)二氟甲基硫醇化的简单方案,该盐可以通过 Tf 2 O 触发的苄基二氟烷基亚砜的亲电活化原位制备。通过该协议, 顺利获得了二氟烷基硫醇化芳烃、杂芳烃、α-二氟烷基硫醇化羰基化合物等, 收率良好。该反应的优点包括容易获得的二氟烷基硫醇化试剂和底物、温和的条件和出色的区域选择性。
