The selective conversion of one inactive C(sp3)-Cl bond of 1,2-dichloroethane (DCE) into C(sp3)-C(sp2) linkages for access to β-chloroethylarenes is presented here. The key to achieve the required reactivity and chemoselectivity in this synthetic method was the utilization of nickel and combinatorial nitrogen ligands as catalytic system. Synthetic advantages of this coupling chemistry included the
本文介绍了1,2-二氯乙烷(DCE)的一个非活性C(sp 3)-Cl键到C(sp 3)-C(sp 2)键的选择性转化,以访问β-氯乙基芳烃。在这种合成方法中实现所需的反应性和化学选择性的关键是利用镍和组合氮配体作为催化体系。这种偶联化学的合成优势包括对β-氯乙基芳烃的步骤简单性,偶联条件的温和性和有效性,以及允许保留的均苄基C-Cl键进行进一步官能团转化的便利性。
