摘要: abstract Reactions of thioketones, sulfines, and thiosulfines were reviewed. Thioaldehydes thioketones formed by the reaction phosphonium ylides with elemental sulfur. Prolonged heating this resulted in formation thiosulfine intermediates, which treated DMAD or thiones to give corresponding adducts. Selenocarbonyl compounds also method. α-Dithiolactone was synthesized di-tert-butylthioketene S-oxide Lawesson's reagent. α-Disulfines isolated thiocamphor derivatives S2Cl2 followed oxidation.
