In the presence of catalytic amounts of tetrakis(triphenylphosphine)palladium(0) and 1,2-bis(diphenylphosphino)ethane, α,β-epoxy ketones isomerize to the corresponding β-diketones in high yields. Both open-chain and cyclic substrates can be used. Possible reaction mechanisms are discussed.
在催化量的四(三苯基膦)钯(0)和1,2-双(二苯基膦基)乙烷的存在下,α,β-环氧酮以高收率异构化为相应的β-二酮。开链和环状底物均可使用。讨论了可能的反应机理。
