## Abstract While 4βchloroxanthione **1** gives with diazomethane the dithiol **2**, it reacts with other diazoalkanes to give the episulfides **3**β**5**, desulfurization of which forms the ethylenes **6** and **7**. Malononitrile and ethyl cyanoacetate react with **1** to give the cyano derivativ
2,5-Dihydro-2,2-diphenyl-1,3,4-thiadiazole (4) eliminates N 2 at -45 Β°C and generates thiobenzophenone S-methylide (5), which is intercepted by dipolarophiles. The 1,3-cycloadditions of 5 with thiones (aromatic and aliphatic thioketones, dithioesters, trithiocarbonate) furnish 1,3-dithiolanes 7, in
