Phenylhydrazine → HCID 21860263, compound

Participants

Reaction Steps

A mixture comprised of 14.7 g (50 mmol) of bis (phenylthio)methylenepropanedinitrile [see Chem. Ber., 99, 2900 (1966)], 6.5 g (60 mmol) of phenylhydrazine and 80 ml of methanol was heated under reflux for 7 hours. The solvent was removed by distillation, and 100 ml of ethanol was added to the residue to crystallize the residue. The crystals formed were taken out by filtration under suction to obtain 13.7 g (47mmols) of the intended product as colorless, needle-like crystals having a melting point of 172° to 173° C. The yield was 94%.
