2-Diphenylphosphinobenzaldehyde is a

phosphine ligand A metal-phosphine complex is a coordination complex containing one or more phosphine ligands. Almost always, the phosphine is an organophosphine of the type R3P (R = alkyl, aryl). Metal phosphine complexes are useful in homogeneous catalysis. Prom ...

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 Chlorodiphenylphosphine is an organophosphorus compound with the formula (C6H5)2PCl, abbreviated Ph2PCl. It is a colourless oily liquid with a pungent odor that is often described as being garlic-like and detectable even in the ppb range. It is ...

Grignard reagent Grignard reagents or Grignard compounds are chemical compounds with the general formula , where X is a halogen and R is an organic group, normally an alkyl or aryl. Two typical examples are methylmagnesium chloride and phenylmagnesium bromi ...

derived from the protected 2-bromobenzaldehyde, followed by deprotection. It can also be derived from (2-lithiophenyl)diphenylphosphine. The compound condenses with a variety of amines to give phosphine-imine and phosphine-amine

ligand In coordination chemistry, a ligand is an ion or molecule with a functional group that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's el ...
