摘要：

The 1.3-dithietane {MelS}(2) (8) is obtained from Meldrum's acid MelH(2) (1, Mel = C6H6O4) and sulphur dichloride in good yield. 8 reacts with the nucleophiles PPh3 and 2,3-dihydro1.3-diisopropyl-4,5-dimethylimidazol-2-ylidene (12, Im) to give the zwitterionic compounds Mel-S-PPh3 (11) and Mel-S-Im (13). Aqueous ammonia gives the dianionic disulfide (NH4)(2)[Mel-S-S-Mel] (14). The crystal structures of 8, 11, and 14 are discussed.
