ResumoAbstract A new version of the epoxyketone → alkynone fragmentation is described. Hydrazones derived from cyclic α,β‐epoxy‐ketones and N‐amino‐aziridines decompose thermally into molecular nitrogen, an olefinic fragment and an acetylenic carbonyl compound (compare scheme 1). The reaction of phenylglyoxal with N‐amino‐phenyl‐aziridine at room temperature produces styrene and diazo‐acetophenone in high yield (compare scheme 3).
