Recent Progress in Developing Thioether-Containing Ligands for Catalysis Applications

Abstract

AbstractThe ligand that stabilizes the metal center is crucial to its catalytic activity. Historically dominated by phosphorus and nitrogen, sulfur has long been little considered as a hetero element for stabilizing a potentially active metal center. However, this situation is changing and we are seeing more and more examples that incorporate this element. This review provides an overview of recent transition-metal-catalyzed reactions with ligands containing neutral sulfur groups, i.e. thioethers. A selection of examples published since 2013 illustrates the diversity of applications of thioether-containing ligands and shows that sulfur should be more widely used in the development of homogeneous catalysis.1 Introduction2 Phosphorus-Thioether Ligands3 Nitrogen-Thioether Ligands4 Oxygen-Thioether Ligands5 NHC-Thioether Ligands6 Cycloolefin-Thioether Ligands7 Conclusion
