fields in calixarene chemistry due to the difficulties in their preparation. The strategy presented in this paper shows that novel tripodal calixcryptands can be conveniently prepared by directly treacing p-tert-butylcalix[n]arenes (n = 4, 6) with a multi-functional polypode reagent, e.g. 1,1,1-tris(tosyloxyethoxyethoxymethyl)propane or tetrakis(tosyloxyethoxyethoxymethyl)methane, under selected conditions
由于制备困难,三足杯状隐密体一直是杯芳烃化学中鲜为人知的领域之一。本文提出的策略表明,通过使用多功能多极试剂(例如 1,1,1-tris)直接追踪对叔丁基杯 [n] 芳烃 (n = 4, 6),可以方便地制备新型三足杯穴状配体。 (甲苯磺酰氧基乙氧基乙氧基甲基)丙烷或四(甲苯磺酰氧基乙氧基乙氧基甲基)甲烷,在选定的条件下。1,2,4-tripodal calix[6]cryptands 的第一个例子已经准备好了。共同制备了新型杯[6]冠和双杯[4]芳烃。介绍了这些新型杯穴状配体对几种碱金属离子、铵和烷基铵离子的提取能力。
