An electrochemical approach with iodoarene as a mediator using recyclable ionic liquids to achieve dibromonative cyclization of 1,n-enynes has been reported. With recyclable bromine sources, in situ generation of iodine(III) compounds through electrochemical oxidation to achieve cyclization, a variety of heterocyclic frameworks containing both vinyl and alkyl bromide groups had been obtained in high yields with good selectivity.
