A simple and useful procedure for the synthesis of azirinescontainingaldehydefunctionality from open chain bromo/chloro-aldehydes at room temperature is reported. The scope of the ring expansion reaction of a number of 3-substituted-2-formyl-azirines has been examined using different oraganometallic catalysts and a variety of Lewis acids.
