General description: p-Toluenesulfonyl chloride is an organic sulfonyl chloride mainly used to convert hydroxyl groups into good leaving group by forming sulfonates.

Application: p-Toluenesulfonyl chloride may be used in the following processes:. In combination with N-methylimidazole for the esterification or thioesterification of carboxylic acids and alcohols or thiols.. As an additive to enhance the yield of symmetrical biaryls via palladium chloride catalyzed homo-coupling of arylboronic acids in the absence of ligands.. As a positive chlorine source for the ?-chlorination of ketones.. Solvent-free tosylation of alcohols and phenols in the presence of heterodoxy acids.. As an activator for reaction between 2-alkynylbenzaldoxime and phenols to form 1-aroxyisoquinolines in the presence of silver triflate.. As a catalyst for the solvent-free preparation of symmetrical bis(benzhydryl)ethers from benzhydrols.
