Phenylhydrazine → HCID 54277863, compound

Participants

Reaction Steps

To a stirred solution of 4.0 grams (0.0204 moles) of 2,2'-azobis (2-isocyanato-propane) (from Example XXXIII) in 20 ml of pentane in a 50 ml erlenmeyer flask was added 4.42 grams (0.0408 moles) of phenylhydrazine and the reaction mixture stirred for 2 hours at room temperature. The solids that formed were filtered off, washed with a small amount of cold acetone and air dried. The tan powder weighed 4.5 grams (54% crude yield). The product melts at 159°-162° C. with decomposition. The infrared spectrum of the product is in agreement with the structure of the proposed compound (urea type carbonyl at 1670 cm-1 and NH bands at 3270 and 3400 cm-1).
