related reagents. Herein, we designed and synthesized the new electrophilic trifluoromethylselenolation reagents, trifluoromethyl selenoxides, which are easy to prepare and easy-to-handle and are not moisture or air sensitive. The selenoxides are successfully applied to metal-free C–H trifluoromethylselenolation of a series of (hetero)arenes.
三氟甲基硒基(CF 3 Se)由于其高Hansch亲油性参数和强吸电子效应而成为合成化学中新兴的氟化基团。三氟甲基硒化受到有限合成方法和相关试剂的阻碍。在此,我们设计并合成了新的亲电子三氟甲基硒化试剂三氟甲基硒氧化物,该试剂易于制备和处理,对水分或空气不敏感。硒氧化物成功地应用于一系列(杂)芳烃的无金属 C-H 三氟甲基硒化。
