The reaction of vinylidenecyclopropanes 1 with diphenylphosphinodithioic acid produces the adducts 3 in good to high yields in toluene upon heating at 100 °C within 1 h, whereas adducts 5 are obtained in excellent yields in reversed regioselectivity from the reaction of 1 with thioaceticacid under identical conditions. The radical reaction processes have been discussed on the basis of deuterium labeling
