CuCl2/8-Hydroxyquinoline-catalyzed α-Arylation of Diethyl Malonate with Aryl Bromides
A general and efficient coupling of aryl bromides with diethyl malonate is presented. The reaction provided the α-arylated diethyl malonates in moderate to good yields with a low loading of CuCl2(5%, molar fraction) and 8-hydroxyquinoline(5%, molar fraction). This method has good compatibility for a wide range of aryl bromides.
