  • Methods of Hydroarylation with Acid Catalysts
    Publication number: 20230027298
    Abstract: Provided are methods of forming a carbon-carbon bond between a first compound and a second compound through a hydroarylation chemical reaction. The methods include contacting the first compound and the second compound in the presence of an acid catalyst. The methods include forming a carbon-carbon bond wherein the first compound includes a first aryl group that is electron-deficient. Provided is a method of generating a quaternary carbon through a hydroarylation chemical reaction.
