Aryl sulfonate esters are versatile synthetic intermediates in organic chemistry as well as attractive architectures due to their bioactive properties. Herein, we report the synthesis of alkyl-substituted benzenesulfonate esters by iron-catalyzed C(sp2)–C(sp3) cross-coupling of Grignard reagents with aryl chlorides. The method operates using an environmentally benign and sustainable iron catalytic
芳基磺酸酯是有机化学中的多功能合成中间体,并且由于其生物活性而具有有吸引力的结构。在此,我们报道了通过铁催化格氏试剂与芳基氯的C(sp 2 )–C(sp 3 )交叉偶联合成烷基取代的苯磺酸酯。该方法使用环境友好且可持续的铁催化系统进行操作,并采用良性尿素配体。多种氯苯磺酸盐以及具有挑战性的含有 β-氢的烷基有机金属化合物都适合这些条件,从而以高收率提供烷基化产物。研究表明,芳基磺酸酯是铁催化芳基氯与格氏试剂发生烷基化 C(sp 2 )–C(sp 3 ) 交叉偶联反应时最具反应性的活化基团。
