## Abstract Phenyl isothiocyanate reacts with butyraldazine in presence of acidic catalysts to form a 2‐pyrazoline (IV) whereas phenyl or benzyl isocyanates under similar conditions yield a mixture of the two isomeric 2‐pyrazolines XIa and XII. On reaction with Ac~2~O, IV gave the 1‐acetyl derivati
