A practical rhodium-mediated arylation of 1,4-quinones has been developed. The corresponding 2-aryl-1,4-quinones were obtained with excellent selectivity and high yields under convenient aerobic reaction conditions.
Various aryl-substituted 1,4-benzoquinone derivatives have been prepared via a palladium-catalyzeddecarboxylativecross-coupling of electron-rich aromatic acids with 1,4-benzoquinones.
