The Newborn Surface of Dull Metals in Organic Synthesis. Bismuth-Mediated Solvent-Free One-Step Conversion of Nitroarenes to Azoxy- and Azoarenes
摘要:
When milled together with bismuth shots, nitroarenes are readily converted to azoxy- and/or azoarenes depending on substrates and conditions employed. Simple extraction with organic solvent followed by evaporation of the resulting dark pasty solid gave the product in good yield.
