The reversible nature of the imine bond formation in CDCl(3) solution has been exploited to exchange substituted for unsubstituted m-phenylenediamine (MPD) units in hemicarcerand octaimines. Moreover, acid-catalyzed imine exchange has been shown to provide a novel mechanism whereby ferrocene (Fc) can be released as an entrapped guest from the hemicarceplex C(2)B(4)&crcldt;Fc dissolved in CDCl(3) to
亚胺键在CDCl(3)解决方案中形成的可逆性质已被用来交换半瓷和八胺中的未取代间苯二胺(MPD)单元。此外,酸催化的亚胺交换已显示出提供了一种新的机制,由此二茂铁(Fc)可以从溶解在CDCl(3)中的半抗体复合物C(2)B(4)&crcldt; Fc作为捕获的客体释放出来。当同时存在过量的MPD和三氟乙酸时,则使用半杀虫剂和C(2)B(4)。
