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

Article abstract of DOI:10.1055/s-1991-26397

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.
