A copper-catalyzed SN2′-selective arylation of allylicchlorides has been achieved using arylboronic esters as nucleophiles. Arylation products were obtained in high yield with a variety of allylicchlorides and arylboronic esters in the presence of a wide range of functional groups. A mechanism is proposed on the basis of the results of stoichiometric experiments and the isolation of the proposed
使用芳基硼酸酯作为亲核试剂,已经实现了铜催化的烯丙基氯化物的S N 2'选择性芳基化。在各种官能团存在的情况下,可以使用多种烯丙基氯化物和芳基硼酸酯以高收率获得丙烯酸化产物。根据化学计量的实验结果和所提出的中间体的分离,提出了一种机理。
