Abstract

Abstract Aryl-and hetero-aryl iodides react under very mild conditions (THF, 25 C) with a Zn (Ag) couple deposited on graphite leading to the corresponding zinc reagents in excellent yields. In the presence of CuCN· 2LiCl or catalytic amounts of Pd (0), these unsaturated zinc species can be acylated, allylated or coupled with iodoalkenes.
