Description and Uses
Tris(o-tolyl)phosphine is an organophosphorus compound. This compound is a white, water-insoluble solid that is soluble in organic solvents. In solution, it slowly converts to the phosphine oxide. As a phosphine ligand, it has a wide cone angle of 194°. Consequently, it tends to cyclometalate when treated with metal halides and metal acetates. Complexes of this ligand are common in homogeneous catalysis.
Tri(o-tolyl)phosphine is used in a ruthenium-catalyzed direct amination of alcohols. It is also used in Suzuki reaction. Further, it is used in the preparation of tri-ortho-phosphinselenide by reacting with selenium as a reagent. In addition to this, it acts as a ligand in coordination chemistry.
