The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Tricyclohexylphosphonium tetrafluoroborate, is researched, Molecular C18H34BF4P, CAS is 58656-04-5, about Nickel- and Palladium-Catalyzed Coupling of Aryl Fluorosulfonates with Aryl Boronic Acids Enabled by Sulfuryl Fluoride, the main research direction is nickel palladium catalyzed cross coupling aryl fluorosulfonate arylboronic acid; one pot phenol sulfuryl fluoride arylfluorosulfonate in situ intermediate; biaryl preparation Suzuki coupling cross coupling.Application of 58656-04-5.
Herein are reported examples of the nickel- and palladium-catalyzed cross-coupling of aryl fluorosulfonates and aryl boronic acids. These reactions occur in good to excellent yields under mild conditions with excellent functional group compatibility employing either Pd(OAc)2 and inexpensive PPh3 or the inexpensive and readily available NiCl2(PCy3)2. Importantly, the in situ conversion of phenol derivatives to the corresponding aryl fluorosulfonate by reaction with sulfuryl fluoride and a base and subsequent cross-coupling to form biaryls in a single pot are described. The combination of inexpensive sulfuryl fluoride and efficient catalysts reported in these methodologies will enable economical Suzuki coupling of phenols in pharmaceutical and agrochem. processes.
After consulting a lot of data, we found that this compound(58656-04-5)Application of 58656-04-5 can be used in many types of reactions. And in most cases, this compound has more advantages.
