Stepwise Selective Reduction of Polynitroarenes Using Isopropanol as a Source of Hydrogen in a Flow-Type Reactor in the Presence of Alumina

Reduction of several polynitroarenes with isopropanol in a flow-type reactor in the presence of Al 2 O 3 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...

Description
Summary:Reduction of several polynitroarenes with isopropanol in a flow-type reactor in the presence of Al 2 O 3 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.
