Carbonylation of (hetero)aryl iodides/bromides with highly deactivated 2-aminopyridines using Pd–Co(CO)4 bimetallic catalysis is accomplished. The use of Co2(CO)8 as a solid CO(g) source enhanced reaction rates observed when compared to CO(g), and excellent yields highlight the versatility of the developed protocol. A wide range of electronically and sterically demanding heterocyclic amines and (hetero)aryl
使用Pd–Co(CO)4双金属催化,可高度失活的2-氨基吡啶与(杂)芳基碘化物/溴化物进行羰基化反应。与CO(g)相比,使用Co 2(CO)8作为固体CO(g)源可提高反应速度,并且出色的收率突出了所开发方案的多功能性。用于本研究的各种电子和空间要求性的杂环胺和(杂)芳基碘化物/溴化物可产生优异的氨基羰基化产物收率。所开发的方法进一步扩展为合成锥虫布鲁西和荧光素酶抑制剂。
