ABSTRACT

Hydrazonoyl halides (1a–e) react with cycloalkanone oximes (2–6) to give substituted heterocyclic spiro compounds (8–11a–e). Reaction of triazaspiro[4.5]dec-2-ene (9b) with acetic anhydride gave the ring transformation product triazole (17b) instead of the N-acetyl derivative (16b).

ACKNOWLEDGMENT

The authors wish to thank Dr. L. Gossen and Dr. W. Schrader, Max-Planck Institut fuer Kohlenforschung, Muelheim, Germany, for obtaining the mass spectra.
