摘要

The catalytic N-alkylation and N-heterocyclization of nitroarenes occur at 180° 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 (PPh 3) 3 and PdCl 2, is effective ...
