    • Treatment of 2-bromoenal 1a under the present reaction conditions without the use of precatalyst 4 did not result in the formation of the alkynal 1a′. This rules out the dehydrobromination of 1a to 1a′ and subsequent generation of the α,β-unsaturated acylazolium intermediate. For a related dehydrobromination of allylic bromo alcohol derivatives, see:, H. Lütjens, S. Nowotny, P. Knochel, Tetrahedron: Asymmetry 1995, 6, 2675.
