用改进的 Vilsmeier反应由 3位未取代的中氮茚合成了一系列 3 -硫代甲酰基中氮茚 (硫醛 ) ,对其在甲醇溶液中哌啶催化下与碘化 1 ,2 -二甲基吡啶盐及碘化 1 ,4-二甲基吡啶盐的缩合反应进行研究 ,高收率地合成了相应含中氮茚环的二甲川菁 ,产物结构经元素分析、红外光谱、1H谱及质谱确证 ,并测定了其在固态下的荧光性质 .结果表明 ,所有的化合物发射波长都在 40 0 nm以上 ,有希望成为发光材料 . A series of 3 - carbamoylindolizines (thioaldehydes) were synthesized from the unsubstituted 3 - indolizine by a modified Vilsmeier reaction. The reaction was catalyzed by piperidine in methanol solution with 1, 2 - bis Methylpyridinium salt and iodinated 1, 4 - dimethylpyridinium salt condensation reaction, the corresponding synthesis with a high yield of indol ring containing dimethylline, the product structure by elemental analysis, infrared spectroscopy, 1H spectra and mass spectra, and its fluorescence properties in solid state were measured.The results show that all the compounds have emission wavelengths above 40 0 ​​nm, promising to be luminescent materials.
