The influence of each condition on the reaction speed and yield was studied, and the optimal conditions were: the ratio of the amount of substance of aromatic amine and heptafluoro-isopropyl iodine was 1:1.1~1.5, the amount of substance of sodium dithionite, sodium bicarbonate, aniline compounds were respectively 1.1~1.3, the amount of substance of phase transfer catalyst TBAB and aniline compounds was 0.05~0.1, the concentration of aniline compound was 0.5~1.0 mol/L, reaction temperature was 10~20 ℃, and the solvent was aether.
最佳结果为:芳胺与七氟异丙基碘的物质的量比1:1.1~1.5,连二亚硫酸钠、碳酸氢钠与苯胺的物质的量分别为1.1~1.3,相转移催化剂四丁基溴化铵与苯胺的物质的量比在0.05~0.1,溶剂总用量使苯胺浓度在0.5~1.0 mol/L;反应温度10~20℃;溶剂采用乙醚。取代基供电子性越强,反应时间越短,产率越高;氨基的对位优先反应,氨基的邻位较难发生反应;且七氟异丙基总是优先取代在芳环电子云密度较高的位置上。
