Preparation of Trimethylphosphine: It can be obtained by using Grignard reagents: 3 CH₃MgBr + P(OC₆H₅)₃ → P(CH₃)₃ + 3 MgBrOC₆H₅. The synthesis is conducted in dibutyl ether, from which the more volatile PMe₃ can be distilled.

Uses of Trimethylphosphine: It is used in the preparation of organic phosphorus compounds and frequently-used phosphine ligand. It is also a highly basic ligand that forms complexes with most metals. In addition, it can react with bromomethyl-benzene to get benzyl-trimethyl-phosphonium; bromide. This reaction needs solvent ethanol. The reaction time is 2 days. The yield is 93%.
