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.
芳基和杂芳基碘化物在非常温和的条件下(THF,25°C)与沉积在石墨上的Zn(Ag)对反应,从而以优异的产率得到相应的锌试剂。在CuCN·2LiCl或催化量的Pd(0)的存在下,这些不饱和锌物质可以被酰化,烯丙基化或与碘代烯烃偶联。
