synthesized by nucleophilic substitution reactions of perfluorocycloalkenes with azoles (i.e., imidazole, triazole) involving simple reaction procedures. Interestingly, these azoles were later found to be reactive not only with the vinylic, but also with the allylic fluorine atoms. This resulted in the substitution of up to six azoles on the fluorinated rings. Stoichiometry plays a key role in determining the
二-和multiazole取代含氟环状制品(2 - 13)中进行了良好容易地合成高收率。它们是通过全氟环烯烃与吡咯(即,咪唑,三唑)的亲核取代反应(包括简单的反应程序)合成的。有趣的是,后来发现这些吡咯不仅与乙烯基具有反应性,而且与烯丙基氟原子也具有反应性。这导致在氟化环上最多取代六个唑。化学计量学在确定取代度中起关键作用。为了进行比较,还研究了N-取代的1-(三甲基甲硅烷基)-咪唑和1-(三甲基甲硅烷基)-1,2,4-三唑的类似反应。所有这些新化合物均通过元素光谱进行了充分表征(19F,1 H,13 C NMR)和热差示扫描量热法(DSC)分析。
