摘要
利用硅胶柱层析方法 ,提纯增效剂 A1得到内 ( endo) N- ( 2 -乙基 )己基 - 1 -异丙基 - 4-甲基二环 [2 ,2 ,2 ]- 5-辛烯 - 2 ,3-二甲酰亚胺 ( 1 )。由 α-松油烯合成外 ( exo) α-松油烯 -马来酸酐加成物 ,再与 2 -乙基己胺反应合成外 ( exo) N- ( 2 -乙基 )己基 - 1 -异丙基 -4-甲基二环 [2 ,2 ,2 ]- 5-辛烯 - 2 ,3-二甲酰亚胺 ( 2 )。利用元素分析、IR和 1H NMR对 1和 2的结构进行鉴定。杀虫增效活性试验证明 :内型结构 ( endo) 1的增效活性强于外型结构 ( exo) 2。
Synergist A 1 was purified to obtain endo N (2 ethyl)hexyl 1 isopropyl 4 methylbicyclo[2,2,2] 5 octene 2,3 dicarboximide(1) with column chromatographic method. exo N (2 ethyl)hexyl 1 isopropyl 4 methylbicyclo[2,2,2] 5 octene 2,3 dicarboximide(2) was synthesized from exo 1 isopropyl 4 methylbicyclo[2,2,2] 5 octene 2,3 dicarboxyl anhydride, which was obtained from α terpinene and maleic anhydride. The structures of 1 and 2 were identified by elementary analysis、IR and 1H NMR. The synergistic tests showed that the synergism toward pyrethroid of 1(endo) is better than 2 (exo).
