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.
