The ring-opening of epoxides with potassium trifluoroborates proceeds smoothly in the presence of trifluoroacetic anhydride under metal-free conditions. The reactions are regioselective and afford a single diastereomer. Both electron-rich and electron-poor aryltrifluoroborates are tolerated.
在三氟乙酸酐存在下,环氧化物与三氟硼酸钾的开环反应在无金属条件下顺利进行。反应具有区域选择性,并产生单一非对映异构体。富电子和贫电子芳基三氟硼酸盐均可被容忍。
