An efficient carbonylative procedure for the synthesis of 3-arylquinoin-2(1H)-ones has been established. Through a palladium-catalyzed aminocarbonylation of benzyl chlorides with anthranils, a variety of 3-arylquinoin-2(1H)-one products were obtained in moderate to excellent yields with good functional group tolerance.

A palladium-catalyzed carbonylative cyclization of benzyl chlorides with o-nitrobenzaldehydes has been developed for the synthesis of 3-arylquinolin-2(1H)-ones. Mo(CO)6 played a dual role as both a CO surrogate and a reductant in this carbonylative transformation.

3-Aryl/alkyl-2-quinolones were synthesized employing microwave assisted multicomponent reaction of 2-iodoanilines, terminal alkynes and oxalic acid dihydrate ((CO2H)2 ? 2H2O) under polystyrene supported palladium (Pd@PS) nanoparticles-catalyzed conditions. The use of a heterogeneous palladium catalyst was explored first time for 2-quinolone synthesis involving carbonylation reaction employing (CO2H)2 ? 2H2O as a solid and bench stable carbon monoxide (CO) source. The reaction exhibited good substrate generality for 2-iodoanilines and alkynes with wide functional group tolerance and good regio-selectivity. The ligand free operation, recyclability of heterogeneous Pd@PS catalyst and use of bench stable C1 source are the invaluable merits of the protocol. (Figure presented.).
