p-Toluenesulfonyl chloride, 1 X 100 g (240877-100G)

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