Application

Tricyclohexylphosphine tetrafluoroborate may be used in the following processes:
  • As a ligand for preparing C-homoaporphine alkaloids via microwave-assisted direct-arylation.
  • To synthesize poly-[9,9-bis(3-propylamide-2-methylpropyl sulfonic acid) fluorene]-co-(4,4′-diphenyl) (PFDBSO3H), which can be employed as a template and doping agent for enhancing the conductivity of poly(3,4-ethylenedioxythiophene) (PEDOT) films.
  • To improve the reactivity of palladium-catalyzed Suzuki-Miyaura cross-coupling reaction between MIDA boronates and less activated alkenyl tosylates.
Used with Ru(cod)Cl dimer to catalyze the dehydrogenative coupling of alcohols and amines to form amide bonds.

General description

Tricyclohexylphosphine tetrafluoroborate (PCy3·HBF4) is an inexpensive and air-stable phosphine ligand, commonly used in cross-coupling reactions.
