Chemie und Industrie
Anwendungen
Verwendensuzuki reactionHindered Phosphine salt employed with a Pd(0)-15-membered, triolefinic, macrocyle in Suzuki cross-coupling reactions of aryl bromides and chlorides. Also used in Heck coupling of non-activated vinyl tosylates with electron deficient olefins.Ligand used in the Pd-catalyzed enantioselective αarylation of N-boc-pyrrolidine.
Darstellung
synthetischeAddition of HBF4 to a solution of tri-tert-butylphosphine in methylene chloride. Separation of the organic layer and removal of the solvent gives analytically pure Tri-tert-butylphosphine tetrafluoroborate.
