Aryl- and hetero-aryl iodides react under very mild conditions (THF, 25 deg 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(O), these unsaturated zinc species can be acylated, allylated or coupled with iodoalkenes.
