Significance
Internal alkynes can be oxidized in a Wacker-type process, using a Pd(II)/Cu(II) catalyst and O2 as an oxidant, into synthetically useful 1,2-diketones. This reaction is highly efficient for a broad range of functionalized substrates including alkynes bearing two alkyl substituents and affords substituted α-diketones in good yields.
