Organozinc compounds of functionalized alkyl iodide carrying an alkoxycarbonyl, cyano or alkenyl group were prepared in high yields under mild conditions (0°C-r.t., 10min in DMF) by the reaction of iodides with an electrogenerated reactive zinc (EGZn). Cross-coupling of the organozinc compounds with various aryl halides in the presence of 5 mol% Pd(P(o-Tol)3)2Cl2 in THF gave the corresponding cross-coupled
通过使碘化物与电生成的反应性锌(EGZn)反应,在温和的条件下(0°Cr.t。,在DMF中为10分钟)以高收率制备带有烷氧基羰基,氰基或烯基的官能化烷基碘的有机锌化合物。有机锌化合物与各种芳基卤化物在THF中有5 mol%Pd(P(o- Tol)3)2 Cl 2的交叉偶联得到相应的交叉偶联产物,产率中等至高。这些交叉偶联反应也可以通过使用利用Pt阴极和Zn阳极的电化学方法在一个步骤和一个罐中完成。
