p-Toluenesulfonic acid (PTSA or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH3C6H4SO3H. It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. The CH3C6H4SO2 group is known as the tosyl group and is often abbreviated as Ts … See more TsOH is prepared on an industrial scale by the sulfonation of toluene. Common impurities include benzenesulfonic acid and sulfuric acid. TsOH monohydrate contains an amount of water. To estimate the total moisture … See more Alkyl tosylates are alkylating agents because tosylate is electron-withdrawing as well as a good leaving group. Tosylate is a pseudohalide. Toluenesulfonate esters undergo nucleophilic attack or elimination. Reduction of tosylate esters gives the hydrocarbon. Thus, … See more • Tosyl • Collidinium p-toluenesulfonate See more • TsOH may be converted to p-toluenesulfonic anhydride by heating with phosphorus pentoxide. • When heated with acid and water, TsOH undergoes hydrolysis to toluene: CH3C6H4SO3H + … See more WebPerforming this reaction in the presence of PtO 2 (5 mol%) and with catalytic amount of PTSA (10 mol%) in MeOH produced the desired compound 2a in a moderate yield (42%, …
