title: Pummerer fragmentation vs. pummerer rearrangement: a mechanistic analysis.
abstract: Depending upon the nature of the substituent at the beta-position of the sulfoxide moiety, a Pummerer reaction can be oriented "at will" towards Calpha-H (rearrangement) or Calpha-Cbeta (fragmentation) bond cleavage.
