General description
Di-p-tolyl sulfone is a di-p-substituted diaryl sulfone. Its synthesis by the sulfonylation of toluene with p-toluenesulfonic acid (TsOH) in the presence of polystyrene supported aluminium triflate (Ps-Al(OTf)3) catalyst has been reported along with its NMR and IR spectra. The gas-phase heats of formation of di-p-tolyl sulfone has been studied. The kinetics and thermodynamics of sulphuric acid assisted cleavage of di-p-tolyl sulfone has been invesitigated.
Application
Di-p-tolyl sulfone may be used in the synthesis of isomeric p-tolylpyridines (α , β and γ ) by photochemical decomposition.
