实验研究表明，醇和胺可以在Ag（III）NCPs的外C=N位发生CF（3）COOAg催化的亲核加成反应，生成C-3-烷氧基化的Ag（III）NCPs，这支持了计算结果，即Ag（III）NCPs外围的C=N键部分地与18 π电子大环共轭体系分离，是活性亲电中心.
Experimental studies demonstrated that alcohols and amines can undergo a CF(3)COOAg-catalyzed nucleophilic addition at the outer C=N position of Ag(III) NCPs, leading to C-3-alkoxylated Ag(III) NCPs, which supports the computational result that the C=N bond on the periphery of Ag(III) NCPs is partially isolated from the 18 pi-electron macrocyclic conjugation system and is the active electrophilic center.
