| Popis: | 94 In this study, ethyl(1-indanylidene)-cyanoacetate(3) has been synthesized by the reaction of 1-indanone with Ethylcyanoacetate, followed by the cyclization with sulfur to given ethyl–2–amino– 8H-indanone[2,1-b]thiophanone-3–carboxylate(5). Compound(5) reacted with acetic anhydride to yield ethyl 2–acetyl-8H-indanone[2,1-b]thiophene-3-carboxylate(7)and with aldehy- des to yield azomethine dyes (C=N) (9) and methine dye(10) and (11), respectively. These compounds were determined by elemental and spectral analysis(FT-IR、1H-NMR and Mass). The solvatochromic behavior of these azo-methine dyes in various solvents were evaluated.
