Popis

General description

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

Application

Used with Ru(cod)Cl dimer to catalyze the dehydrogenative coupling of alcohols and amines to form amide bonds.

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.
