The ring expansion reactions of 1,3-oxathiolium salts (1) using NaN3 and an I2-aq NH3 system resulted exclusively in the formatiom of 1,4,2-oxathiazines (3) by incorporation of a nitrogen atom into the C-O bond in 1.On the other hand, the reaction of 1 wi

N,N-Dialkyl-N'-arylthioureas react with phenacyl halides to give 2-arylimino-5-phenyl-1,3-oxathioles (I), 3-aryl-2-arylimino-4-phenyl-4-thiazolines (III), aryl isothiocyanates and N,N'-diarylthioureas.I reacts with heterocumulenes like phenyl isocyanate and phenyl isothiocyanate to give 3,4-diaryl-2-arylimino-4-thiazolines, N,N'-diarylthioureas, arylacetylenes and COS or CO2.Mechanisms of formation of the various products have been proposed, based on TLC monitoring at regular time intervals.These are independently supported by chemical reactions.
