Catalytic Reduction of ortho- and para-Azidonitrobenzenes via tert-Butoxide Ion Mediated Electron Transfer
摘要:
The reduction of a range of substituted azidonitrobenzene derivatives to the corresponding aniline is described. The chemoselective reaction proceeds cleanly and in good yield, generating minimal waste products. The process involves a thiazolium salt derived species which is proposed as a radical anion relay, with tert-butoxide as the stoichiometric reductant.

spectroscopic methods; the solid state structures of some of the compounds are confirmed by X-ray diffraction techniques. The synthesized materials decompose in the range of 195–308 °C. Most of the –CF3 and –NO2 groups-bearing aryl triazoles exhibit good densities and acceptable detonation characteristics. Some of the fluorine containing polytriazole-bearing compounds showed positive heats of formation.
