Methyldiphenylphosphine is the organophosphine with the formula CH3(C6H5)2P, often abbreviated PMePh2. It is a colorless, viscous liquid. It is a member of series (CH3)3-n(C6H5)2P that also includes n = 0, n = 1, and n = 3 that are often employed as ligands in metal phosphine complexes.
Methyldiphenylphosphine is prepared by reaction of chlorodiphenylphosphine with methyl Grignard reagent:
