摘要：

Reduction of several polynitroarenes with isopropanol in a flow-type reactor in the presence of Al2O3 catalyst was studied. Temperature-controlled highly selective reduction of one, two, or three nitro groups in all the studied polynitroarenes proved to be feasible. N-alkylation of the reaction products was the predominant side reaction at high temperatures, except for the reduction of 2,7-dinitronaphthalene: in this case, a considerable amount of alkoxylated product was obtained. Benzo[c]cinnoline was the main product of reduction of 2,2'-dinitrobiphenyl.
