A palladium-catalyzed cross-coupling between aryl esters and anilines is reported, enabling access to diverse amides. The reaction takes place via activation of the C–O bond by oxidative addition with a Pd–NHC complex, which enables the use of relatively non-nucleophilic anilines that otherwise require stoichiometric activation with strong bases in order to react. High yields of aromatic, aliphatic
N-(pyridine-2-yl)amides in water from ketones and 2-aminopyridine via direct oxidative C–C bond cleavage has been developed. A series of ketones, including more challenging inactive aromaticketones substituted with diverse long-chain alkyl groups, were selectively converted to N-(pyridine-2-yl)amides. Furthermore, the protocol can be applied to aryl alkyl carbinols to afford the corresponding amides in moderate

amide compounds, including heterocyclic amide compounds, were obtained with moderate to good yields ranging from 31–88% by using copper iodide (CuI) to catalyze the oxidative amidation between aldehydes and amines under solvent-free conditions at room temperature in air.
