Benzoylhydrazine → HCID 21431282, compound

Participants

Reaction Steps

To a solution of 4.02 grams (0.0295 moles) of benzoylhydrazine in 25 ml of methanol in a 50 ml erlenmeyer flask was added 6.82 grams (0.0295 moles) of 1-t-butylazo-1-isothiocyanatocyclohexane and the reaction mixture stirred for 6 days at room temperature. The methanol was evaporated under reduced pressure leaving a pale yellow solid weighing 9.0 grams (75% crude yield). The product melted with decomposition at 190°-193° C. The infrared spectrum of the product had amide bands at 1640 and 1690 cm-1, a strong band at 1550 cm-1 [-N(H)CS] and weak NH bands from 3100-3300 cm-1. The isothiocyanate band at 2040 cm-1 was absent.
