| titleOfInvention | Reduction of certain 2,2{40 -disubstituted azoxybenzenes and azobenzenes to corresponding hydrazobenzenes |
| abstract | Certain 2,2''-disubstituted hydrazobenzenes, including 2,2''dichlorohydrazobenzene, 2,2''-dimethylhydrazobenzene, and 2,2''dimethoxyhydrazobenzene are produced from the corresponding 2,2''azoxy or azobenzene by a variation of the classical Bechamp reaction for the preparation of anilines, using iron filings and dilute acid. The reaction is accelerated by the employment of small amounts of lead as a reaction promoter and by employment of a solvent and preferably also a cosolvent. When applied to the preferred 2,2''-dichloro starting materials, the reaction is especially valuable in that it produces exceptionally high yields and purity of desired product with a minimum of amine and other byproducts. |
