摘要：

It has been reported that π-hypervalent sulfur plays an important role in effecting cycloaddition of iminothiazolines to activated acetylenes,2 nitriles,3 isothiocyanates,4 and alsoin similar reactions involving 1,2-dithiole-3-thiones.5 We recently reported a unique example of rapid equilibrium due to acid-catalyzed bond switch at π-hypervalent sulfur.6 We now describe a ring-transformation equilibrium of the 1,2,4-thiadizole ring in neutral solution which can be understood as due to bond switch at π-hypervalent sulfur. © 1979, American Chemical Society.
