Visible-Light-Mediated Decarboxylative Coupling of Aromatic Carboxylic Acids with Aryl Methyl Ketones to Unsymmetrical 1,2-Diketones
A transition-metal-free and operationally simple strategy has been developed for the synthesis of unsymmetrical 1,2-diketones via a visible-light-induced decarboxylative arylation–oxidation cascade. Readily available aromatic carboxylic acids serve as convenient aryl precursors, and Eosin Y acts as an inexpensive organ...
