Abstract
Abstract An efficient synthesis of 1, 2, 4-dithiazolidine-3, 5-diones (1) from chlorocarbonylsulfenyl chloride (3) plus O-dimethylaminoethyl-N-alkyl or aryl thiocarbamates (4) has been worked out. In this synthesis, 1, 2, 4-thiadiazolidine-3, 5-diones (5) have been shown to arise as low-level by-products, and experiments were conducted to elucidate the mechanism of the side reaction. N, N′-Dimethyl-1, 2, 4-thiadiazolidine-3, 5- ...
