摘要

Treatment of aromatic nitro compounds with sodium borohydride in alkaline ethanol in the presence of a catalytic amount of diaryl ditelluride at room temperature affords the Corresponding azoxy compounds selectively in fair to excellent yields. Under reflux aromatic azo compounds are obtained as major products. In situ generated sodium arenetellurolate (ArTeNa) is the active species to reduce nitroaromatics into aromatic nitroso compounds, ...
