The 2-aminomalondialdehyde bis 2 and some of its N-monosubstituted derivatives 7a-d as well as the o-carboxy benzoyl malondialdehyde 12 have been prepared.With heterocyclic imonium salts these amino malondialdehyde derivatives form, by a twofold condensation reaction, the γ-acylamino-substituted pentamethine cyanine dyes 15a-c, 17, and 18a-b, the UV/Vis and 13C NMR spectra of which are recorded with respect to the influence of the γ-substituent on these spectra. - Key words: 2-Aminomalondialdehyde Derivatives, γ-Acylaminopentamethinecyanine Dyes, UV/Vis Spectra, 13C NMR Spectra
