Specifically, the introduction of charges increase the solubility of the resulting ligand in polar media allowing the derived metal complexes to be utilized in highly polar solvents such as ionic liquids, or to be easily separated from typical organic media. On the other hand, the presence of a cationic group in close proximity to the donor position weakens the σ-donor ability of the P-atom when compared with neutral analogues, and concomitantly enhances the π-acceptor character of the resulting ligand. In this Highlight Review these aspects are overviewed, putting special emphasis on the implications for transition metal catalyzed processes. Recent developments are critically evaluated and future perspectives for this exciting area of ligand design are discussed."],["dc.identifier.doi","10.1246/cl.180810"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62557"],["dc.language.iso","en"],["dc.relation.issn","0366-7022"],["dc.relation.issn","1348-0715"],["dc.title","Applications of α-Cationic Phosphines as Ancillary Ligands in Homogeneous Catalysis"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
