Application

Benzenesulfonic acid monohydrate (PhSO3H. H2O) can be used as:
  • A catalyst to synthesize α,β-unsaturated amides via Pd-catalyzed selective aminocarbonylation of styrenes with nitroarenes.
  • A reactant to prepare amino acid benzyl ester salts for the study of gelation in nonpolar solvents.
  • A catalyst for the conversion of oxydipropionitrile (nitrile) to di-n-propyl-oxydipropionate (ester).
