NMP-mediated chlorination of aliphatic alcohols has been developed for the synthesis of alkyl chlorides. This facile, efficient and practical approach used simple and readily available aryl sulfonyl chlorides as the chlorination reagent for the construction of C–Cl bond in good to excellent yields with mild conditions and broad substrate scope.

Paragraph 0021; 0022, (2017/01/17)
The invention provides a method for preparing chlorohydrocarbons from alcohols by using aryl sulfonyl chloride as a chlorination agent. The method comprises the following steps: heating alcohols and aryl sulfonyl chloride in N,N-dialkyl substituted amide to react for 30 minutes, cooling the reaction product to room temperature, adding dichloromethane and water, carrying out extraction and skimming, washing the organic layer with saturated saline water, drying with anhydrous sodium sulfate, steaming to remove the solvent, and carrying out further separation and purification to obtain the chlorohydrocarbons. The method has the characteristics of cheap and accessible chlorination agent, simple technical process, short reaction time and the like, can obtain high reaction under the condition that the aryl sulfonyl chloride consumption is approximate to the stoichiometric quality, and can remove the reaction byproduct aryl sulfonic acid from the reaction mixture.
