Abstract
A spacious Fe(ii)-iminopyridine self-assembled cage complex can catalyze the oxidative dimerization of alkanethiols, with air as stoichiometric oxidant. The reaction is aided by selective molecular recognition of the reactants, and the active catalyst is derived from the Fe(ii) centers that provide the structural vertices of the host. The host is even capable of size-selective oxidation and can discriminate between alkanethiols of identical reactivity, based solely on size.
摘要
一种宽敞的铁（II）-亚氨基吡啶自组装笼状配合物可以催化链烷硫醇的氧化二聚反应，以空气作为化学计量氧化剂。该反应通过反应物的选择性分子识别得到辅助，活性催化剂源自提供主体结构顶点的铁（II）中心。主体甚至能够进行尺寸选择性氧化，并且仅基于尺寸就能区分具有相同反应活性的链烷硫醇。
