    Description / Table of Contents: Efforts into a Novel Caprolactame Synthesis. II. Rearrangement of 3,3-Pentamethylene Oxaziridine to Caprolactame3,3-Pentamethylene-oxaziridine 1 is converted to caprolactame 2 by flash pyrolysis at 300 °C. In the presence of catalytic amounts of vanadium compounds the rearrangement proceeds in boiling benzene or toluene with yields up to 95 percent. A homolytic mechanism is discussed and made plausible by radical alkylation of acetyl acetonates.
    Notes: 3,3-Pentamethylen-oxaziridin 1 läβt sich durch Flash-Pyrolyse bei 300 °C in Caprolactam umlagern. In Gegenwart katalytischer Mengen von Vanadinverbindungen läuft die Umlagerung bereits in siedendem Benzol oder Toluol mit Ausbeuten bis zu 95% ab. Es wird ein homolytischer Mechanismus diskutiert und durch radikalische Alkylierung von Acetylacetonaten wahrscheinlich gemacht.
