TBHP/I2-promoted oxidative coupling of acetophenones with amines at room temperature under metal-free and solvent-free conditions for the synthesis of α-ketoamides
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

A simple, efficient and practical copper-catalyzedaerobicoxidative synthesis of α-ketoamides from aryl methyl ketones, aliphatic amines and N-iodosuccinimide (NIS) has been developed. The one-pot reaction may proceed smoothly at room temperature in the open air. The possible mechanism for the formation of α-ketoamides was proposed. Molecular oxygen in air functions as both an oxidant and an oxygen
