Applicazioni

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.

Note

Light sensitive. Incompatible with strong oxidizing agents.

Letteratura

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).
