Abstract
Reaction of phosphonium ylides with excess sulfur afforded the corresp onding thiosulfines, which were trapped with maleic anhydride to give the corresponding cycloadducts (1,2-dithiolanes) in good yields. Inter mediary thiosulfines were also formed by sulfurization of thiobenzophe nones with elemental sulfur to give the 1,2-dithiolanes in moderate yi elds.
