  日期：——

  A practical Pd(PPh3)4/DBU catalytic system for the synthesis of pharmaceutically relevant aminopyridine nitrile intermediates, as well as a variety of other aryl nitriles using non-toxic K4[Fe(CN)6] has been developed. The key features of our new protocol for cyanation lie in that the reaction can be carried out with readily available Pd(PPh3)4 under mild and green conditions, even without the assistance of other ligands.

  一种用于合成具有药物相关性的氨基吡啶腈中间体的实用Pd(PPh3)4/DBU催化体系，以及其他多种使用无毒K4[Fe(CN)6]的芳基腈，已经开发出来。我们新方案中氰化的关键特点在于，反应可以在温和且环保的条件下，使用易于获得的Pd(PPh3)4进行，甚至无需其他配体的辅助。
