Abstract: Abstract Substituted merocyanine dyes were obtained by Knoevenagel condensation between formylated arylbenzothiazole and quaternary 2-alkylbenzothiazoles. The condensations were performed in the presence of sodium methoxide and the products were obtained with excellent yields after simple… read more here.
