Abstract: Synthetic method of asymmetry polyarylamino-benzaldehydes by the selective formylation of polyarylamines in Vilsmeier-Haack reaction was studied. Five polyarylamino-benzaldehydes, 4-N-methylphenylamino-benzaldehyde, 4-N-(n-butyl)-phenylamino-benzaldehyde, 4-diphenylamino-benzaldehyde, 4-N-phenyl-diphenylamino-benzaldehyde, 4-N-phenyl-(4′-diphenylamino)diphenylamino-benzaldehyde were synthesized by the selective formylation of the polyarylamines with POCl3 and DMFin the yields of 67%—92%. The structures of these aldehydes were characterized by MS, 1H NMR, IR. The studied results showed that the yields and selectivity of asymmetry polyarylamino-benzaldehydes were found to relate with the reaction time, structures of polyarylamines and the molar ratio of the reactants.

Key words: Polyarylamine, Benzaldehyde, Synthesis, Formylation
