Metal-organic framework (MOFs) compositions based on nitrogen donor-based organic bridging ligands, including ligands based on 1,3-diketimine (NacNac), bipyridines and salicylaldimine, were synthesized and then post-synthetically metalated with metal precursors, such as complexes of first row transition metals. Metal complexes of the organic bridging ligands could also be directly incorporated into the MOFs. The MOFs provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of asymmetric organic transformations. The solid catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.
基于以氮为供体的有机桥联配体,包括基于1,3-二酮亚胺(NacNac)、联吡啶和柳酸亚胺的金属-有机框架(MOFs)组成物被合成,然后用金属前驱体如第一行过渡金属的络合物进行后合成金属化。有机桥联配体的金属络合物也可以直接并入MOFs中。MOFs提供了一个多功能的、可回收和可重复使用的单点固体催化剂家族,用于催化各种不对称有机转化。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。
