Copper-catalyzed dehydrogenative reaction: synthesis of amide from aldehydes and aminopyridine
摘要:
We have developed a highly efficient method in the presence of copper catalyst to form amides from aminopyridines and aldehydes. This method is simple, environmental benign and has practical advantages in the amide synthesis. (C) 2013 Elsevier Ltd. All rights reserved.

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
