Applications
Tri-tert-butylphosphonium tetrafluoroborate is a ligand used in the palladium-catalyzed enantioselective alfa-arylation of N-boc-pyrrolidine. It is also used with a palladium(0)-15-membered, triolefinic, macrocyle in Suzuki cross-coupling reactions of aryl bromides and chlorides. Further, it is used in the Heck coupling of vinyl tosylates with olefins.

Solubility
Soluble in methylene chloride and chloroform. Slightly soluble in terahydro furan. Insoluble in hexane, toluene and water.

Notes
Incompatible with strong oxidizing agents and halogens.
