Cross-coupling of (hetero)arylthiols with arylzinc reagents via C–S cleavage was performed under transition-metal-free conditions. The reaction displays a wide scope of substrates and high functional-group tolerance. Electron-rich and -deficient (hetero)arylthiols and arylzinc reagents can be employed in this transformation. Mg2+ and Li+ ions were demonstrated to facilitate the reaction.
(杂)芳基硫醇与芳基锌试剂通过C–S裂解的交叉偶联是在无过渡金属的条件下进行的。该反应显示出广泛的底物范围和高官能团耐受性。富电子和不足的(杂)芳基硫醇和芳基锌试剂可用于该转化中。已证明Mg 2+和Li +离子可促进反应。
