Potassium (trifluoromethyl)trimethoxyborate is introduced as a new source of CF3 nucleophiles in copper‐catalyzed trifluoromethylation reactions. The crystalline salt is stable on storage, easy to handle, and can be obtained in near‐quantitative yields simply by mixing B(OMe)3, CF3SiMe3, and KF. The trifluoromethylation reagent allows the conversion of various aryl iodides into the corresponding benzotrifluorides
(三氟甲基)三甲氧基硼酸钾是在铜催化的三氟甲基化反应中作为CF 3亲核试剂的新来源而引入的。结晶盐储存稳定,易于处理,只需将B(OMe)3,CF 3 SiMe 3和KF混合即可以接近定量的产率获得。三氟甲基化试剂可在催化量的Cu I / 1,10-菲咯啉络合物存在下,在温和,无碱的条件下,将各种芳基碘化物高产率地转化为相应的苯并三氟化物。
