Formal propagation of (hetero)arylamine is achieved via a one-pot Buchwald–Hartwig C–N cross-coupling and nitro reduction sequence, enabling a rapid modular synthesis of diverse amino-di(hetero)arylamines from (hetero)arylamines and halogenated nitrobenzenes. Various functionalized aromatic amines with different electronic and steric environments can be efficiently prolongated to formally incorporate another arylamino fragments. This approach has been successfully applied in the synthesis of more than forty amino-di(hetero)arylamines. The applicability of this method has also been demonstrated in the synthesis of oligoanilines and the tyrosine-kinase inhibitor Imatinib.

A light-sensitive, diazonium group-containing polycondensation product is described which comprises (a) an optionally substituted diphenylamine-dianzonium salt I. (b) a compound corresponding to the formula II wherein R4 is H, alkyl or acyl, and R5 is an optionally substituted aromatic radical, and (c) a compound corresponding to the formula III wherein R6 and R7 are H, alkyl, or acyl and R8 is the radical of a compound selected from the group consisting of aromatic hydrocarbons, phenols, phenolethers, aromatic thioethers, aromatic heterocyclic compounds, and organic acid amides, with the radicals resulting from compound II being directing linked to the units of the diazonium salt I. In the production of the polycondensation product, I is first condensed with II and then with III. The product is suitable for use as a light-sensitive substance in recording materials, particularly in printing plates, and yields light-hardening products which have an increased oleophilicity.
