The acetal forms of glutaconaldehyde (2,6-dialkoxypyrans, 1,1,5,5-tetraalkoxy-2-pentenes, 5,5-dialkoxy-2-pentenals, and 1,3,5,5-tetraalkoxy-1-pentenes) are capable of reacting with quaternary salts of heterocyclic bases containing an active methyl group in acetic anhydride solution and in the presence of triethylamine with the formation of tricarbocyanine dyes. Syntheses are reported of unsubstituted thio-, indo-, and quinotricarbocyanines and derivatives with various substituents in the polymethine chain. The reaction proceeds readily upon heating glutaconaldehyde derivatives with quaternary salts in acetic anhydride in the presence of triethylamine.
