Phosphine-catalyzed synthesis of unsymmetrical 1,3-bis- and trisphosphorus ligands

Article abstract of DOI:10.1055/s-0029-1217176

Phosphine-catalyzed umpolung γ-additions of phosphorus pronucleophiles on alkynes bearing phosphinoyl (P=O) or phosphinothioyl (P=S) moieties have been explored. The reaction leads to bis- or trisphosphorus subunits that can be useful for the preparation of chelating ligands. Georg Thieme Verlag Stuttgart.
