Supramolecular catalysis based on discrete heterometallic coordination- driven metallacycles and metallacages

摘要

The rational design and facile construction of discrete heterometallic supramolecular catalysts have precipitated a surge of research interest in emulating sophisticated natural catalysts with well-defined cavities and inlaid active sites, allowing conversion of encapsulated substrates with high chemo-, regio-, and stereoselectivity. This review briefly highlights such discrete, heterometallic, coordination-driven metallacycles and metallacages obtained by the strategic utilization of a range of predesigned building blocks in the supramolecular chemist's toolkit. The two major synthetic strategies toward these metallaarchitectures are presented, and special attention has been paid to discussing both the fascinating structures and the unique catalytic performance of various heterometallic macrocycles and cages.
