Diphenylphosphine Cas 829-85-6

Organic Phosphine Ligand Precursors: Used for the synthesis of phosphine ligands—such as DPPE, DPPP, and BINAP—employed in transition-metal-catalyzed reactions including Suzuki, Heck, and Sonogashira couplings.
Organic Synthesis Intermediates: Utilized in the preparation of tertiary phosphines, phosphide lithium salts, Wittig-Horner reagents, and phosphonium salts; applied in the synthesis of chiral catalysts and pharmaceutical intermediates.
Reducing / Addition Reagents: The P–H bond exhibits both nucleophilic and reducing properties, enabling addition reactions with activated olefins and carbonyl compounds.
