Metal-organic framework (MOFs) compositions based on post¬synthetic metalation of secondary building unit (SBU) terminal or bridging OH or OH2 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.
本文介绍了金属有机框架(MOFs)组合物,该组合物基于用金属前体或其他合成后操作对二级构建单元(SBU)末端或桥接羟基或OH2基团进行合成后金属化。这些 MOFs 提供了一个可回收和可重复使用的单位固体催化剂家族,可用于催化各种不对称有机转化,包括苄基 C-H 键的区域选择性硼酰化和硅酰化、烯烃、亚胺、羰基、硝基烯烃和杂环的氢化、氢硼化、氢膦化和环化反应。固体催化剂还可以集成到流动反应器或超临界流体反应器中。
