This method involves a simple, visible-light-driven Z-selective synthesis of methylthio-substituted 1,4-enedione in a single step promoted by Selectfluor. Dimethyl sulfoxide is used as both the 'thio' source and the solvent, with molecular iodine and potassium persulfate as catalyst and oxidant, and white light (CFL-30W) as the light source. The proposed mechanism includes a Kornblum reaction followed by aldol reaction.
