摘 要:对于邻位、间位取代苯胺与丙烯腈发生单氰乙基反应生成相应的N-氰乙基邻位取代苯胺和N-氰乙基间位取代苯胺的过程,AlCl3具有高的催化活性。在芳香胺/丙烯腈/AlCl3=1/1.10/(0.05~0.10)(摩尔比)、反应温度60~80℃,反应时间6~10h的条件下,反应的收率达87%~90%。用毛细管气相色谱法分析了单氰乙基化反应中各组份的含量;所合成的7种N-氰乙基邻位取代苯胺和N-氰乙基间位取代苯胺用DTA-TG、UV、IR、1HNMR和EA进行了物性和结构表征。Mono-cyanoethylation addition reactions of o-substituted or m-substituted anilines with aerylonitrile have been carried out in the presence of AlCl3 , resulting in N-β-cyanoethyl-o-substituted anilines, N-β-cyanoethyl-m- substituted anilines in high yield. Under the conditions of mole ratio of the reactants as substituted anilines: acrylonitrile:AlCl3= 1: 1.10:(0.05 - 0. 10) , the temperature of 60 -80 ℃ for 6 - 10 h, the yields of mono- cyanoethyl substituted anilines were 87% - 90 % ,and capillary gas chromatographic determination method was used for the contents analysis of N-β-cyanoethyl-o-substituted anilines or N-β-cyanoethyl-p-substituted anilines among mono-cyanoethylation reactions. All of products were characterized by DTA-TG, UV-Vis, FTIR, ^1H NMR, and elemental analyses.
