New approaches in supramolecular transition metal catalysis: self-assembling ligands, molecular capsules and supramolecular anchoring

Supramolecular chemistry has grown into a major scientific field over the last thirty years and has fueled numerous developments at the interfaces with biology and physics, clearly demonstrating its potential at a multidisciplinary level. Simultaneously, organometallic chemistry and transition metal catalysis have matured in an incredible manner, broadening the pallet of tools available for chemical conversions. The interface between supramolecular chemistry and transition metal catalysis has received surprisingly little attention. It provides, however, novel and elegant strategies that could lead to new tools for the search of effective catalysts. In this contribution we describe some of these new approaches to transition metal catalyst development, which evolve from a combination of supramolecular strategies and rational ligand design that have been subject of investigations in our lab in the recent past. These examples include a template-ligand approach to catalyst encapsulation, formation of bidentate ligands by self-assembly and the supramolecular immobilization of catalysts to arrive at recoverable homogeneous catalysts.
