Structure Determination of Unusual Rearrangement Products of S ‐(1‐Alkenyl)sulfoximides by Collisionally Activated Dissoication Mass Spectrometry (CAD‐MS) The Molecular ions of s ‐(l‐alkenyl)‐ ‐N ‐( p ‐tolyl)sulfoximides 1 are transformed into the N (phenylsufenyl)sulfonamides 3 + by a 1,2‐migration of the alkenyle group to the O‐atom of the sulfoximide function followed by a 2,3‐sigmatropic rearrangement. The structure of the production e has been unambiguouslydetermined by the CAD method, showing the identity of the ion e ( m/z 368) obtained from 1a and from 4a .
