3，6-二(4，4，4-三氟-1，3-丁二酮基)-9-乙基咔唑的合成与电子光谱

Synthesis and electronic absorption spectral property of 3,6-bis(4,4,4-trifluoro-1,3-butyldiketone)-9-ethylcarbazole

咔唑分子经SN1烷基化、Friedel-Crafts双乙酰化和Claisen缩合3步反应,合成了标题化合物,其结构经元素分析、IR、1HNMR和MS表征,还研究了中间体和目标化合物的电子吸收光谱行为。

Based on carbazole molecular designing, a novel bis-β-diketone of 3,6-bis （4,4,4-trifluoro- 1,3-butyldoketone）-9-ethyl-carbazole was synthesized through reactions of SN1 alkylation, the Friedel-Crafts bi-acylation reaction and the Claisen condensation reaction, which had not been reported up to date. The structure of the said product was characterized by IR, ^1HNMR, MS and elemental analysis. The electronic absorption spectral properties were also studied.
