Heterogeneous Catalytic Transfer Hydrogenation of 4-Nitrodiphenylamine to p-Phenylenediamines

Article abstract of DOI:10.1039/c39880001275

p-Phenylenediamine analogues have been prepared from 4-nitrodophenylamine (1) by catalytic transfer hydrogenation in one stage; the process can be extended to the general condensation of a nitro compound with an alcohol (with Raney nickel as catalyst) or a ketone (with palladium as catalyst).
