DDQ‐Catalyzed Oxidative CO Coupling Of sp3 CH Bonds With Carboxylic Acids

Da-ddy, DDQ: By using catalytic amounts of DDQ combined with MnO2 as oxidant, an efficient oxidative CO coupling of benzylic sp3 CH bonds with carboxylic acids affords a series of carboxylic esters in 70–98 % yields. A wide range of functional groups and various carboxylic acids are tolerated. The reaction involves both CH functionalization and CO bond formation.
