The catalytic N-alkylation and N-heterocyclization of nitroarenes occur at 180 deg C under a carbon monoxide pressure of 70 atm and in the presence of aldehyde and such transitionmetal complexes as rhodium and palladium complexes, thus giving 2,3-dialkyl-substituted quinolines and (dialkylamino)arenes in good yields.The product selectivity depends greatly on the catalysts: a binary catalyst, RhCl(PPh3)3 and PdCl2, is effective for the N-heterocyclization, while
