Tricyclohexylphosphine tetrafluoroborate

Application

Tricyclohexylphosphine tetrafluoroborate (PCy3·HBF4) serves a versatile role in modern chemistry, acting as a non-pyrophoric and air-stable phosphine ligand crucial for various stoichiometric and catalytic processes. Its primary purpose is to facilitate cross-coupling reactions, particularly enhancing the reactivity of palladium-catalyzed Suzuki-Miyaura reactions between MIDA boronates and less activated alkenyl tosylates. This compound is also pivotal in the synthesis of significant pharmaceutical intermediates, such as the JAK2 inhibitor BMS-911543, a potential treatment for myeloproliferative disorders, and in the preparation of Lapatinib intermediates. Additionally, it assists in forming C-homoaporphine alkaloids using microwave-assisted direct-arylation and synthesizing conductive materials like PFDBSO3H to enhance the performance of PEDOT films. Overall, Tricyclohexylphosphine tetrafluoroborate is an affordable and efficient ligand that replaces neat phosphine in diverse synthetic applications.
