Process for the preparation of aryl hydrazines
Production of aryl hydrazines (I) comprises reacting an aryl hydrazine disulfonate (II) with water and an inorganic acid in an inert organic solvent at 0-100 degrees C and treating the resulting aryl hydrazine salt with a base. Production of aryl hydrazines of formula (I) comprises reacting an aryl...

Zusammenfassung: | Production of aryl hydrazines (I) comprises reacting an aryl hydrazine disulfonate (II) with water and an inorganic acid in an inert organic solvent at 0-100 degrees C and treating the resulting aryl hydrazine salt with a base. Production of aryl hydrazines of formula (I) comprises reacting an aryl hydrazine disulfonate of formula (II) with water and an inorganic acid in an inert organic solvent at 0-100 degrees C and treating the resulting aryl hydrazine salt with a base: R -R = H, 1-4C alkyl, 1-4C alkoxy, halogen or OH; Ar = phenyl or naphthyl; M , M = H, NH4, or alkali(ne earth) metal. |
