Olefin substrates can be converted to the corresponding enones or 1,4-enediones in very good yields in short reaction times using a Cu(II) 2-quinoxalinol salen complex as the catalyst and tert-butyl hydroperoxide (TBHP) as the oxidant via allylic activation. The reaction tolerates many additional functional groups.
