An efficient approach to α,β-unsaturated α′-iodo ketones directly from α,β-unsaturated ketones by selective iodination at the α′-position in the presence of copper(II) oxide/iodine offers high yields, short reaction times, inexpensive reagents, mild reaction conditions, ease of manipulation, and the formation of cleaner products.
