DESCRIPTION
General description
p-Toluenesulfonyl chloride is an organic sulfonyl chloride mainly used to convert hydroxyl groups into good leaving group by forming sulfonates.[1]
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.[2]
- As an additive to enhance the yield of symmetrical biaryls via palladium chloride catalyzed homo-coupling of arylboronic acids in the absence of ligands.[3]
- As a positive chlorine source for the ?-chlorination of ketones.[4]
- Solvent-free tosylation of alcohols and phenols in the presence of heterodoxy acids.[5]
- As an activator for reaction between 2-alkynylbenzaldoxime and phenols to form 1-aroxyisoquinolines in the presence of silver triflate.[6]
As a catalyst for the solvent-free preparation of symmetrical bis(benzhydryl)ethers from benzhydrols.[7]
