摘要：

Thiatriazoline 4a decomposes in acetone and yields a thermolabile crystalline material, identified as the 1,2,4-oxathiazole derivative 6a on the basis of ir, H-1 and C-13 nmr spectroscopy. It degrades to 7a in the crystalline state as well as in solution. Cycloaddition-elimination reactions of 6a with isothiocyanates proceed rapidly and furnish the same products as previously obtained from 4a. Some other reactions of 4 with carbonyl compounds were briefly investigated and provide evidence for the formation of unstable 1,2,4-oxathiazolidines.
