Abstract:
The reaction of primary 2,3‐allenols with iodine (I 2 ) afforded 2,5‐dihydrofurans while that of readily available 1‐aryl or 1‐methyl substituted 2,3‐allenols with bromine (Br 2 ), N ‐bromosuccinimide (NBS), I 2 or N ‐iodosuccinimide (NIS) formed the not easily available but synthetically useful 3‐halo‐3‐alkenals and 2‐halo‐2‐alkenyl ketones with good selectivity and yields via a sequential electrophilic interaction of X + with the allene moiety, 1,2‐aryl or 1,2‐proton shift, and H + elimination process.
