Mr. Biscoe et Aj. Fry, Dual reaction pathways in the magnesium-mediated synthesis of aziridines from benzal halides and imines, TETRAHEDR L, 42(15), 2001, pp. 2759-2762
Reaction between benzal dihalides, benzaldehyde imines, and magnesium in et
her affords aziridines in modest yields. Two mechanistic pathways for aziri
dine formation are discerned. One path involves nucleophilic attack by an a
lpha-halo Grignard species on the imine; the other involves electrophilic a
ttack on imine by phenylcarbene to afford an azomethine ylide. (C) 2001 Els
