Acetonitrile, propyne, and acetylene react essentially quantitatively with S2NAsF6 to give the hexafluoroarsenate salts of 5-methyl-1,3,2,4-dithiadiazolium, 4-methyl-1,3,2-dithiazolium, and 1,3,2-dithiazolium respectively, the structures of the former two salts being determined by X-ray crystallography; the cations have been reduced chemically and electrolytically to form long-lived free redicals identified
