Abstract

The partial reduction of nitroarenes with hydroxides in alcoholic media is a venerable yet very direct approach to the synthesis of symmetrical azoxyarenes. Herein, the first application of this method to nitropyridines is disclosed, presenting its adaptation with these challenging but important substrates.
