Metal-organic framework (MOFs) compositions based on post¬synthetic metalation of secondary building unit (SBU) terminal or bridging OH or OH

groups with metal precursors or other post-synthetic manipulations are described. The MOFs provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of asymmetric organic transformations, including the regioselective boryiation and siiylation of benzyiic C—H bonds, the hydrogenation of aikenes, imines, carbonyls, nitroarenes, and heterocycles, hydroboration, hydrophosphination, and cyclization reactions. The solid catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.
基于后合成金属化的次级构建单元(SBU)端部或桥接的OH或OH2基团与金属前体或其他后合成操作的金属有机框架(MOFs)组成物被描述。这些MOFs提供了一系列多功能的可回收和可重复使用的单位固体催化剂,用于催化各种不对称有机转化,包括对苯基C—H键的区域选择性硼化和硅基化,烯烃、亚胺、醛酮、硝基芳烃和杂环化合物的加氢,氢硼化,氢磷化和环化反应。这些固体催化剂也可以集成到流动反应器或超临界流体反应器中。
