2-Diphenylphosphinobenzaldehyde is a phosphine ligand with the formula (C6H5)2PC6H4CHO. It is a yellow solid that dissolves in common organic solvents.
Synthesis and reactions 2-Diphenylphosphinobenzaldehyde was first prepared by the reaction of chlorodiphenylphosphine with the Grignard reagent derived from the protected 2-bromobenzaldehyde, followed by deprotection.Schiemenz, Guenter P.; Kaack, Hermann "Aromatische Phosphine mit Substituenten zweiter Ordnung, XIII. Triarylphosphine mit mehreren Carbonyl-Funktionen durch Grignard-Synthese (Aromatic phosphines with second order substituents. XIII. Preparation of triarylphosphines with several carbonyl functions by Grignard synthesis)" Justus Liebigs Annalen der Chemie 1973, vol. 9, pp. 1480-93. . It can also be derived from (2-lithiophenyl)diphenylphosphine.
The compound condenses with a variety of amines to give phosphine-imine and phosphine-amine ligands.
