Allgemeine Beschreibung
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.
l?uterung methode
Crystallise the sulfone repeatedly from Et2O or EtOH. It has been purified by zone melting. [Beilstein 6 H 419, 6 II 395, 6 III 1405, 6 IV 2174.]
