Palladium-catalysed aminocarbonylation of diiodopyridines

Add time:07/19/2019    Source:sciencedirect.com

The aminocarbonylation of 2,5- and 2,3-diiodopyridine, as well as 2-chloro-3,4-diiodopyridine with carbon monoxide and various primary and secondary amines was carried out using palladium-catalysed aminocarbonylation. The formation of the products containing carboxamide and ketocarboxamide functionalities was accompanied by the formation of imides when ortho-diiodo compounds were used as substrates. In spite of several possible reaction pathways, most of the products were synthesised as major product in yields of synthetic interest by the appropriate modification of the reaction conditions.
