ABSTRACT:
Organic substituted hydrazines are prepared by introducing chloramine optionally carrying one or two alkyl groups into an intensely agitated or finely divided liquid, substantially anhydrous phase of a liquid primary or secondary amine or a solution of a primary or secondary amine in an inert solvent. Especially phenylhydrazine can be obtained in a very good yield from chloramine and aniline. The organic substituted hydrazines are important intermediates for syntheses, especially of pharmaceutical products.
