2-Diphenylphosphinobenzaldehyde is an organophosphorus compound with the formula (C6H5)2PC6H4CHO. It is a yellow solid that dissolves in common organic solvents. The compound condenses with a variety of amines to give phosphine-imine and phosphine-amine ligands. It was first prepared by the reaction of chlorodiphenylphosphine with the Grignard reagent derived from the protected bromobenzaldehyde followed by deprotection. It can also be derived from (2-lithiophenyl)diphenylphosphine.
