通过化学选择性金属-卤素交换制备了一些二烯基咪唑，并将其用于关环复分解反应。基本上所有的区域异构体排列都参与复分解，但4-乙烯基-5-烯丙基咪唑明显例外，条件是咪唑N3原子被质子化。(C)2003爱思唯尔科技有限公司版权所有。
The preparation of a number of dienylimidazole via chemoselective metal-halogen exchange and their utility in ring-closing metathesis is described. Essentially all regioisomeric permutations participate in metathesis with the notable exception of 4-vinyl-5-allylimidazoles, provided that the imidazole N3 atom is protonated.
