A hypervalentiodine(III)–CF2SO2Ph compound (3) has been successfully prepared with selective nucleophilic reaction using PhSO2CF2SiMe3 reagent, and this previously unkown compound 3 was found to act as a new electrophilic (phenylsulfonyl)difluoromethylation reagent for a variety of S-nucleophiles under very mild reaction conditions.
使用PhSO 2 CF 2 SiMe 3试剂通过选择性亲核反应成功制备了高价碘(III)–CF 2 SO 2 Ph化合物(3),发现该以前未知的化合物3可作为新的亲电子基团(苯磺酰基)在非常温和的反应条件下,用于各种S-亲核试剂的二氟甲基化试剂。
