Xu, Jiaxi,Jiao, Peng
, p. 1491 - 1493 (2002)
1-Aryl-α,β-unsaturated ketones were directly aziridinated, N-unsubstituted, in a one-pot reaction with satisfactory yields by N,N′-diamino-1,4-diazoniabicyclo[2.2.2]octane dinitrate, a nitrogen-nitrogen ylide precursor, in the presence of sodium hydride.
