A robust and porous Cd(ii)-MOF based on a bent imidazole-bridged ligand was synthesized and post-synthetically functionalized with linear alkyl chains to afford imidazolium salt (IM)-type triphase transfer catalysts for organic transformations. The imidazolium salt decorated Cd(ii)-MOF-IM exhibits typical solid phase transfer catalytic behavior for the azidation and thiolation of bromoalkane between aqueous/organic phases. Moreover, they can be easily recovered and reused under the PTC conditions. Cd(ii)-MOF-IM herein created a versatile family of solid phase transfer catalysts for promoting a broad scope of reactions carried out in a biphasic mixture of two immiscible solvents.
基于弯曲咪唑桥连配体合成了一种坚固且多孔的镉（II）-金属有机框架（MOF），并通过线性烷基链进行后合成功能化，以提供用于有机转化的咪唑盐（IM）型三相转移催化剂。咪唑盐修饰的镉（II）-MOF-IM在水相/有机相之间对溴代烷烃的叠氮化和硫醇化反应表现出典型的固相传转移催化行为。此外，它们在相转移催化条件下可以轻松回收和重复使用。本文中的镉（II）-MOF-IM创建了一个通用的固相传转移催化剂家族，用于促进在两种不混溶溶剂的双相混合物中进行的广泛反应。
