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:
- Cl(C6H5)2P + CH3MgBr → CH3(C6H5)2P + MgBrCl
Selected derivatives:
- The phosphine oxide OPMePh2, prepared by treatment with hydrogen peroxide.[1]
- The coordination complex MoH4(PMePh2)4, prepared by treatment of MoCl4(PMePh2)2 with sodium borohydride in the presence of excess ligand.[2]
- The coordination complex CoCl2(PMePh2)2, prepared by treating cobalt(II) chloride with the phosphine.[3]
- The phosphine-borane H3BPMePh2 prepared by treating the phosphine with borane.[4]
