The preparation and the rearrangement of the first diaryl(acyloxy)sulfonylaminospiro-λ4-sulfane 1 are reported with the molecular structures of 1 and those of the product 2 determined by X-ray diffraction; this work demonstrates that the formation of the rearrangement products (2 or 4) depends on the N-substituent of the starting spiro-λ4-sulfane precursor, the sulfoxide 3 or cyclic imide 5.
