accomplished by thermally or photolytically induced decompositions of O-acyl derivatives of N-hydroxypyridine-2-thione or other thiohydroxamic esters of 6-phenylthio-4-hexenoic acid 11 in the presence of an excess of radicophilic olefins, afforded the 2-vinylcyclopentane derivatives 13 in 50–90% yields, while decompositions of thiohydroxami esters or 6-phenylthio-4-hexynoic acids 24, under the same
