Azoxybenzenes are important intermediates in industrial chemistry,and have many applications in the production of dyes,indicators and liquid crystals.In this paper,we describe a novel method for the preparation of azoxybenzenes via the reduction of the corresponding nitroarenes by β-CD/NaOH in water.Several azoxybenzenes were synthesized in moderate to high yields.The reaction conditions were optimized,and a tentative reaction mechanism was proposed.This method is simple,economic and environmentally friendl...
