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.
Preferred phosphine ligand for use in combination with Pd salts in the Heck-type coupling reactions of vinylic halides. For examples, see Palladium(II) acetate, 10516. For a review of the Heck reaction, see: Org. React., 27, 345 (1982).
The Pd-catalyzed amination of bromoarenes with 1-Boc-piperazine, L13363, in the presence of this ligand, provides a route to arylpiperazines of potential pharmacological interest: Tetrahedron Lett., 39, 2219 (1998).
