remote C(sp3)–H arylation of unsymmetrical 1-(o-iodoaryl)alkyl ethers with cyanoarenes for the site selective synthesis of α-(hetero)aryl ethers is developed. With the introduction of cyanoarenes as both aryl sources and electron transfer mediators, this method includes an iodoarene-driven strategy to enable the regiocontrollable formation of two new bonds, one C(sp2)–H bond, and one C(sp2)–C(sp3) bond
开发了一种碘芳烃驱动的不对称1-(邻碘芳基)烷基醚与氰基芳烃的远程电还原C(sp 3 )–H芳基化反应,用于α-(杂)芳基醚的位点选择性合成。通过引入氰基芳烃作为芳基源和电子转移介体,该方法包括一种碘芳烃驱动策略,能够区域可控地形成两个新键,一个 C(sp 2 )–H 键和一个 C(sp 2 )– C(sp 3 ) 键,在一个反应步骤中通过卤素原子转移 (XAT)、氢原子转移 (HAT)、自由基-自由基偶联和脱氰化的顺序。
