Methyldiphenylphosphine
Methyldiphenylphosphine is the organophosphine with the formula CH32P, often abbreviated PMePh2. It is a colorless, viscous liquid. It is a member of series 3-n2P 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:
Selected derivatives:
- The phosphine oxide OPMePh2, prepared by treatment with hydrogen peroxide.
- The coordination complex MoH44, prepared by treatment of MoCl42 with sodium borohydride in the presence of excess ligand.
- The coordination complex CoCl22, prepared by treating cobalt(II) chloride with the phosphine.
- The phosphine-borane H3BPMePh2 prepared by treating the phosphine with borane.
