  • Gold-Catalyzed C-C Cross-Coupling of Boron- and Silicon-Containing Aryl Compounds and Aryldiazonium Compounds by Visible-Light
    Publication number: 20200031731
    Abstract: The present invention relates to a method for producing (functionalized) biaryls by employing a visible-light-driven, gold-catalyzed C—C cross-coupling reaction system involving boron- and silicon-containing aryl compounds and aryldiazonium compounds. Moreover, the present invention relates to the use of such boron- and silicon-containing aryl compounds and aryldiazonium compounds, as well as related gold catalysts, in the manufacture of (functionalized) biaryls.
