Synthesis and reactions

edit

2-Diphenylphosphinobenzaldehyde was first prepared by the reaction of chlorodiphenylphosphine with the Grignard reagent derived from the protected 2-bromobenzaldehyde, followed by deprotection.[1][2] 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.[3][4]
