A Simple Reduction Method of Azo-Compounds to Amines Using Fe Powder in the Presence of NH4Cl
摘要:
A series of azo-compounds were reduced to related aromatic amines in the presence of Fe powder and ammonium chloride. This one step protocol led to the formation of products in middle to high yields, especially when electron releasing substituted aromatic azo-compounds were reduced.

Flashvacuumpyrolysis of phenylazonaphthols and nitrosonaphthols at 700°C and 0.02 Torr yielded quinoline, isoquinoline, indene and naphthols (and aniline only from the phenylazo derivatives). Similar FVP of p-nitroso and p-phenylazophenol gave pyridine. Also, FVP of phenanthraquinonemonophenylhydrazone and monooxime gave phenathridine and fluorenone. The formation of the heterocyclic system was assumed

Hydrated zirconia has been found to be an efficient and reusable catalyst for the regiospecificacylations for of arenes and selective reductions of azobenzenes to produce benzo-phenones and hydrazobenzenes respectively.
synthesis of diazoniumsalts is historically an important transformation extensively utilized in dye manufacture. However the highly reactive nature of the diazonium functionality has additionally led to the development of many new reactions including several carbon-carbonbond forming processes. It is therefore highly desirable to determine optimum conditions for the formation of diazonium compounds
