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
2,5-和2,3-二碘吡啶以及2-氯-3,4-二碘吡啶与一氧化碳以及各种伯胺和仲胺的氨基羰基化反应是通过钯催化的氨基羰基化反应进行的。当使用邻二碘代化合物作为底物时,形成含有羧酰胺和酮羧酰胺官能团的产物伴随着酰亚胺的形成。尽管有几种可能的反应途径,但通过适当地改变反应条件,大多数产物被合成为主要产物,具有合成目的的产率。
