Abstract

An iodine-induced sulfonylation of quinoline-2-thiones with sodium arenesulfinates as sulfur sources for the synthesis of 4-aryl-2-(arylsulfonyl)quinoline derivatives is described. The 4-aryl-2-(arylsulfonyl)quinoline derivatives can be obtained in a moderate to good yields. This C–S bond cleavage and C–S cross-coupling proceeds in the absence of a metal under inexpensive and nontoxic conditions and it displays a broad substrate scope.
