A highly reactive electrophilic bromodifluoromethylthiolating reagent, α-cumyl bromodifluoro-methanesulfenate 1, was prepared to allow for direct bromodifluoromethylthiolation of aryl boron reagents. This coupling reaction takes place under copper catalysis, and affords a large range of bromodifluoromethylthiolated arenes. These compounds are amenable to various transformations including halogen exchange
制备了高反应性的亲电溴二氟甲基硫醇化试剂,α-枯基溴二氟甲基甲磺酸盐1,以允许芳基硼试剂的直接溴二氟甲基硫醇化。该偶联反应在铜催化下发生,并提供了大范围的溴二氟甲基硫醇化的芳烃。这些化合物可进行各种转化,包括与[18 F] KF / K222进行卤素交换,该过程可从相应的芳基硼酸频哪醇酯分两步获得[18 F]芳基SCF3。
