Abstract
Aminocarbonylation of alkenyl and aryl iodides in the presence of 4-amino-4H-1,2,4-triazole as N-nucleophile was carried out in the presence of palladium catalysts. Both types of substrates have shown high chemoselectivity toward carboxamides, i.e. practically no double carbon monoxide insertion resulting in 2-ketocarboxamides took place. The results have been rationalised on the basis of mechanistic aspects of aminocarbonylation.
