Radical reduction of alkyl halides and aerobic oxidation of alkyl aromatics are reported using water-soluble container compounds (1 and 2). The reductions involve -dihalides (4-8 and 10) with radical initiators in cavitand hosts with varied binding affinities. Product distributions lead to general guidelines for the use of dynamic supramolecular systems with fast reactions. Binding of guest substrates in the hosts must show high affinities (Ka > 103 M-1) to ensure that the reactions take place under confinement in the containers (11 and 12).

Cavitands 中的自由基反应揭示了亲和力对动态超分子系统的影响

使用水溶性容器化合物 (1 和 2) 报道了烷基卤化物的自由基还原和烷基芳烃的有氧氧化。还原涉及 α-二卤化物（4-8 和 10）与自由基引发剂在具有不同结合亲和力的空腔主体中。产品分布导致使用具有快速反应的动态超分子系统的一般指南。宿主中客体底物的结合必须显示出高亲和力 (Ka > 103 M-1)，以确保反应在容器 (11 和 12) 的限制下进行。
