The aminoformylation of cyclic 1-alkoxy-1,3-dienes by the Vilsmeier complex obtained from dimethylformamide and phosphorus oxychloride was investigated.The salts of the dianils of glutaconaldehyde derivatives with six-membered rings in the conjugation chain were synthesized by treatment of the reaction products with aniline in an acidic medium.They were used for the production of the corresponding tricarbocyanine dyes.
