Photoacid generators (PAGs) based on N-acyl-N-phenylhydroxylamines for carboxylic and sulfonic acids

Simple and efficient photoacid generators (PAGs) for carboxylic and sulfonic acids based on N-acyl-N-phenylhydroxylamines have been demonstrated. Irradiation of o-carboxylates and thermally rearranged o-arenesulfonates of N-acyl-N-phenylhydroxylamines using UV light (≥254 nm) in aqueous methanolic solution resulted in efficient generation of carboxylic and sulfonic acids, respectively. The carboxylic acid generation ability of N-acyl-N- phenylhydroxylamines was found to be dependent on their N-acyl substituents. Further, polymer bearing o-arenesulfonates of N-acyl-N-phenylhydroxylamine was synthesized and demonstrated as PAG for sulfonic acids.

Internal Mobility in the Ion Pairs during Aromatic Rearrangement of O-Sulfonyl-N-phenylhydroxylamines

In the rearrangement of O-alkyl- or O-arylsulfonyl-N-benzoyl-N-phenylhydroxylamines 3 to aminophenols 4, the internal mobility in the ion pair intermediates depends both on the size of the alkyl groups and on the interaction with the protic solvent, as wa
