Various primary and secondary amines, including amino acid methyl esters, were used as nucleophiles in palladium-catalysed aminocarbonylation of 2-iodopyridine, 3-iodopyridine and iodopyrazine. N-Substituted nicotinamides and 3-pyridyl-glyoxylamides (2-oxo- carboxamide type derivatives) of potential biological importance can be obtained from 3- iodopyridine as a result of simple and double carbon monoxide insertions, respectively. ...
