Abstract

Depending on the reaction conditions, dimethylaminomethylenemalonaldehyde aminal acetal reacts with malonodinitrile or alkyl cyanoacetates to give various neutral or ionic cross-conjugated polynitriles. Cation-anionic cyanine dyes were obtained from tri- and tetracyanopolymethine salts. The conformation and geometric parameters of the tetramethyl 3-dimethylaminomethylenepenta-1,4-diene-1,1,5,5-tetracarboxylate molecule were established by X-ray diffraction analysis.
