Abstract
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.
