The (E)-iodoalkylidene lactones which can be formed by reaction of an alkene with N-iodosuccinimide and an acetylenic acid with subsequent free-radical cyclisation, are readily transformed into iodine free alkylidene lactones by photolysis. Under different reaction conditions, the photolyses yield mixtures of (E) and (Z)-iodovinylidene lactones.
