Palladium-Catalyzed Homocoupling of Arylboronic Acids and Esters Using Fluoride in Aqueous Solvents

Palladium-Catalyzed Homocoupling of Arylboronic Acids and Esters Using Fluoride in Aqueous Solvents

Abstract Homocoupling of both arylboronic acids and esters has been found to proceed using catalytic amounts of Pd II and stoichiometric amounts of TBAF under air atmosphere at room temperature, offering a mild and efficient protocol for the synthesis of symmetrical biaryls via C(SP 2 )-C(SP 2 ) bon...

Zusammenfassung:Abstract Homocoupling of both arylboronic acids and esters has been found to proceed using catalytic amounts of Pd II and stoichiometric amounts of TBAF under air atmosphere at room temperature, offering a mild and efficient protocol for the synthesis of symmetrical biaryls via C(SP 2 )-C(SP 2 ) bond formation. Aryl boronic acids bearing bromide substitution form polyphenylenes.
