An efficient nickel-catalyzed cyanation of aryl sulfonates, fluorosulfonates, and sulfamates with Zn(CN)2 was developed, which provides a facile access to the nitrile products in generally good to excellent yields. The reaction is accomplished by using NiII complex as the precatalyst and DMAP as the additive. The method also displays wide functional group compatibility; for example, keto, methoxy,
开发了一种有效的镍催化的芳基磺酸盐,氟磺酸盐和氨基磺酸盐与Zn(CN)2的氰化氰化物,该方法可轻松获得腈产品,通常收率良好,收率极佳。该反应是通过使用Ni II配合物作为预催化剂和DMAP作为添加剂来完成的。该方法还显示了广泛的功能组兼容性。例如,在反应过程中,酮,甲氧基,N,N-二甲基氨基,氰基,酯和吡啶基具有良好的耐受性。
