✦ Synopsis

Absinz& The selected diaikyi dithioethers l,S-dithiocane, 1,4-dithiepane, 1,4-dithione, and 2,6_dithiaheptone are readily monoaIkyIoted in nitromethane by tert-butyl tMij7uoromethanesulfonyI-3-hydro~perogproponoate, 4 to give the corresponding suifonium salt peresters 2a-c, and 3 in good yieId. Loser j7osh photoIysis of these compounds affords the known hue-sulfur, three-electron stabilized cation radicals 24 b, and 5 which were characterized by optical absorption spectroscopy.
