Under the motto “Chemistry—our life, our future”, it is a worldwide celebration of the achievements of chemistry and its contributions to the well‐being of humankind. As part of our own contribution...
The effects of introducing ionic functionalities in phosphine ligands on the coordination chemistry of these ligands and the catalytic behavior of the corresponding metal complexes are reviewed. The steric and electronic consequences of such functionalizations are discussed. Apart from these steric and electronic effects, the presence of charged groups often leads to additional, supramolecular interactions...
