Trimethylphosphine is an organophosphorus compound with the formula P (CH 3) 3, commonly abbreviated as PMe 3. This colorless liquid has a strongly unpleasant odor, characteristic of alkylphosphines. The compound is a common ligand in coordination chemistry. It is a pyramidal molecule with approximate C3v symmetry.

One unique feature of the phosphine ligand is that it allows convenient change of electronic effect without undergoing much change in its steric effects. For example, PBu 3 and P(O i Pr) 3 have similar steric effects but vary in their electronic effects.

Trimethylphosphine (PMe 3) is an electron-rich phosphine ligand used as a reagent in Mitsunobu reaction. It can be used: In transformation of azides into carbamates; [1] aziridines to azidoalcohols; [2] and ketoximes to ketones with 2,2′-dipyridyl diselenide.

Phosphine complexes are most commonly made through ligand substitution processes—the exchange of one ligand for another on a metal center. One interesting method utilizes tertiary N-oxides to essentially “oxidize off” a CO ligand, leaving behind an open coordination site that may be filled by a phosphine.
