Cas no 983-80-2 ((Z)-1,2-Bis(diphenylphosphino)ethene)

(Z)-1,2-Bis(diphenylphosphino)ethene is a bidentate phosphine ligand widely used in coordination chemistry and homogeneous catalysis. Its rigid (Z)-ethene backbone ensures precise geometric control, facilitating the formation of stable metal complexes with well-defined coordination environments. The diphenylphosphino groups provide strong electron-donating properties, enhancing catalytic activity in cross-coupling, hydrogenation, and hydroformylation reactions. This ligand is particularly valued for its ability to stabilize low-oxidation-state metal centers, improving catalyst longevity and selectivity. Its air-sensitive nature necessitates handling under inert conditions, but its consistent performance in asymmetric synthesis and transition-metal catalysis makes it a preferred choice for advanced synthetic applications.
