| Introduction | Tri (O-toluene) phosphine can be used as a ligand in coupling reactions. Tris (O-toluene) phosphine can be obtained by reduction of Tri-o-tolyl phosphine oxide or by preparation of O-bromotoluene by Grignard reaction. |
| Use | Tris (O-methylphenyl) phosphorus is a phosphorus catalyst. It can be used for Rhodium-catalyzed hydrogenation, Suzuki-Miyaura cross-coupling reactions, and the Heck reaction. as a ligand, used in the coupling reaction of The catalyst of Heck reaction, organic intermediate. ligands for ruthenium-Catalyzed Direct Amination of alcohols ligands for ruthenium-catalyzed Amination of alcohols. |
| preparation | Tri-o-tolylphosphine oxide (32.0 mg,0.1 mmol,1.0 eq) and oxalyl chloride (0.15 mmol,1.5eq.) Mix in chloroform-d1(1 ml). The reactor was charged with 80 bar of H2. The mixture was heated to 130°C for 18 hours. The solvent was removed under reduced pressure. The residue was purified by Silica Gel chromatography (cyclohexane) to give tris (O-toluene) phosphine. |
