Several kinds of aminovinyl compounds were prepared by the condensation of diphenylformamidine or 2, 2′, 5, 5′-tetramethylformamidine with alkyl (or allyl) halides of the heterocyclic compounds possessing oxazole, benzoxazole, thiazole, benzothiazole or quinoline nucleus and a methyl group in the 2- or 4-position. Fifteen kinds of trimethinecyanines were also prepared by the condensation of these aminovinyl compounds with alkyl or allyl halides of various heterocyclic compounds possessing methyl at 2-position under the presence of acetic anhydride and anhydrous sodium acetate.
