Chemistry of Heterocyclic Compounds Aims and scope

Abstract

δ-Alkoxy-δ-methylbutadienyl salts were obtained by condensation of acetoacetaldehyde tetraethylacetal with quaternary salts of nitrogen-containing heterocyclic bases. δ-Methyl-substituted tetramethylidynehemicyanines were obtained by the reaction of the acetal with quaternary salts of heterocyclic bases and amines in pyridine. β-Methyl-substituted dicarbocyanine and α-methyl-substituted tetramethylidynemerocyanine dyes were synthesized.
