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:

Selected derivatives:
*The
phosphine oxide
Phosphine oxides are phosphorus compounds with the formula OPX3. When X = alkyl or aryl, these are organophosphine oxides. Triphenylphosphine oxide is an example. An inorganic phosphine oxide is phosphoryl chloride (POCl3).

*The
phosphine-borane
In chemistry, phosphine-boranes are organophosphorus compounds with the formula R3−nHnPBH3. They are Lewis acid-Lewis base adducts derived from organophosphines (PR3−nHn) and borane (BH3). They are generally colorless or white solids. Since ...
