本研究利用1-indanone、氰基乙酸乙酯合成Ethyl(1-indanylidene)-cyanoanetate (3),再與硫粉進行環化反應得到Ethyl-2-amino-8H-Indanone [2,1-b]thiophanone-3–carboxylate(5)。並用Ethyl-2-amino-8H-Indanone [2,1-b]thiophanone-3–carboxylate(5)當中間體在醋酸酐中反應得到Ethyl 2–acetyl-8H-indanone[2,1-b]thiophene -3 -carboxylate(7)然後與含醛基化合物得到azo-methine(C=N)(9)及methine(C=C)(10)、(11)化合物。
所有合成之化合物經光譜分析(UV、IR、1H-NMR及MS等)來確定結構。並分別在不同溶劑下測定其紫外/可見光吸收光譜,探討不同極性對最大吸收波長之影響。
關鍵字: 1-Indanone、醛類、次甲基
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.
Keyword: 1-Indanone、aldehyde、methine
