Iodine in dimethyl sulfoxide as a new general reagent for the preparative oxidation of 1,2-diarylethenes and 1,2-diarylethynes to aromatic 1,2-diketones

1,2-Diarylethenes and 1,2-diarylethynes are readily converted to the corresponding 1,2-diketones in high yield using the reagent iodine in dimethyl sulfoxide. Alkynes in these reactions are more reactive than alkenes.
Chemoselective oxidation of carbon-carbon double or triple bonds to 1,2-diketones with DMSO-based reagents

HBr/DMSO selectively oxidizes the double bond in (E)-1-(2-phenylethenyl)-4-(phenylethynyl)benzene (1) to 1,2-diketone 2. However, 12/DMSO and PdCl2/DMSO oxidize only the triple bond in 1 to 1,2-diketone 3. A similar trend of chemoselectivity is shown for the oxidation of (E)-1,4-diphenyl-1-buten-3-yne (6) with the DMSO-based reagents.
