the regioselective introduction of a vinyl trifluoromethylthioether to remote unactivated C(sp3)—H bonds. The cascade process involves the vinyl radical-mediated 1,5-hydrogen atom transfer (HAT) and remote vinyl migration. During the transformation, inert C—H and C—C bonds are consecutively cleaved under mild conditions. The reaction features good functional group tolerance, broad substrate scope,
本文描述了将乙烯基三氟甲基硫醚区域选择性引入远程未活化的C(sp 3)-H键的有效方案。级联过程涉及乙烯基自由基介导的1,5-氢原子转移(HAT)和远程乙烯基迁移。在转化过程中,惰性CH键和CC键在温和条件下连续裂解。该反应具有良好的官能团耐受性,广泛的底物范围和高的区域/立体选择性。
