Application

p-Toluenesulfonic acid monohydrate (p-TsOH·H2O) may be used as a catalyst in the synthesis of the following:Unsymmetrical benzils.Highly substituted piperidines.1,3,5-Trisubstituted benzenes by trimerization of alkynes.Triazoloquinazolinone and benzimidazoquinazolinone derivatives.1,3,5-Trisubstituted pyrazoles derivatives.Selenated ketene dithioacetals.

General description

p-Toluenesulfonic acid monohydrate, an oxonium salt, is an inexpensive and easy to handle organic catalyst used in organic synthesis. The study of its crystalline structure shows that it is monoclinic with P21/c space group. Its solubility in aqueous sulfuric acid solutions has been studied.
