A facile and convenient protocol for the reduction of nitro‐arenes and deoxygenation of heteroarenes N‐oxides under transition metal and additive free conditions has been developed. The strategy allows the selective reduction of poly‐nitroarenes as well as the efficient deoxygetaion of a variety of N‐oxides containing heteroarenes including benzofuroxanes and phenzines with a broad substrate scope

N,N,N',N'-tetraalkyaminoazoxybenzene derivatives were conveniently prepared by the coupling of N,N-dialkylnitrosoaniline in the presence of acetone and KOH. The reaction mechanism was proposed and investigated, and the structure of compound 3b was also confirmed by single crystal X-ray diffractometry.
