Abstract

The required thiosulfonates 2 were prepared either by the reaction of PhSO2Na with disulfides [7] or by the reaction of PhSO2SNa with various benzylic halides in N, N- dimethylformamide [8](see Supporting Information). Alternatively, the benzylic o-(o- iodophenyl) phenylthio derivatives 1 can also be synthesized from 4 through the two-step preparation of the chloromethyl thioether 5, which was obtained in 72% overall yield.[9] ...
