Abstract The combination of diphenyl sulfoxide and oxalyl chloride was used to accomplish the dichlorination of olefins, in which chlorodiphenylsulfonium salt generated in situ was proposed to be the real active species as a chloronium ion source. Graphical Abstract

Abstract A facile chlorolactonization of alkenoicacids by treatment with diphenyl sulfoxide/oxalyl chloride has been developed. The reaction can generate various chlorolactones in moderate to good yields, wherein the chlorodiphenylsufonium salt derived from diphenyl sulfoxide/oxalyl chloride serves as the source of Cl+.
