Acid-catalysed hydrolysis and protonation behaviour of N-arylpropane-1,3-sultams
Abstract
The acid-catalysed hydrolyses of some N-(para-substituted phenyl)propane-1,3-sultams have been studied in aqueous acidic solutions. The rate maxima observed are shown to be consistent with an A-2 mechanism in which extensive protonation of the substrate occurs. Values of pKBH+ for the sultams have been determined.
