Cycloaddition Elimination Reactions of 4-Aryl-5-arylimino-1,2,4-dithiazolidin-3-ones (Mustard Oil Oxides)

4-Aryl-5-arylimino-1,2,4-dithiazolidin-3-ones (1) react with isocyanates, isothiocyanates, and cyanic acid esters by exchange of the COS-part from 1 affording thiadiazole and dithiazole derivatives 4, 5, 6, or 12.The reaction products are able to give fur

Synthesis and Reactivity of 1,2,4-Oxathiazolidin-3-imines

Thiatriazolin 4a decomposes in acetone and yields a thermolabile crystalline material, identified as the 1,2,4-oxathiazole derivative 6a on the basis of ir, 1H and 13C nmr spectroscopy.It degrades to 7a in the crystalline state as well in solution.Cycloaddition-eliminiation 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.

Mechanism of the Cycloaddition-Elimination Reactions of 4-methyl-5-phenylimino-Δ3-1,2,3,-thiatriazoline with Alkyl and Aryl Isothiocyanates

The formation of thiadiazolidines 3a-c and dithiazolidines 4a-c and 5a-b from the title reactions has been studied in detail under a variety of conditions.On the basis of kinetic measurements, isomerizations studies and cross experiments a mechanism is pr
