中文摘要：
以咔唑为原料,碳酸二乙酯为烷基化试剂,碳酸铯和三乙基苄基氯化铵为共催化剂,经烷基化反应绿色合成了N-乙基咔唑,其结构经1H NMR和HR-ESI-MS确证。在最佳反应条件[咔唑200 mmol,碳酸二乙酯1.2 eq.,碳酸铯（0.05 eq.）和三乙基苄基氯化铵（0.05 eq.）为催化体系,于180℃反应3 h]下,产率99%。
英文摘要：
N-ethylcarbazole was synthesized by alkylation reaction,using carbazole as the material,diethyl carbonate as the alkylating reagent and Cs2CO3/ TEBAC as the cocatalyst. The structure was confirmed by1 H NMR and HR-ESI-MS. Under the optimized conditions[carbazole 200 mmol,diethyl carbonate 1. 2 eq.,Cs2CO30. 05 eq.,TEBAC 0. 05 eq.,at 180 ℃ for 3 h],the yield was up to 99%.
