In the presence of catalytic amounts of tetrakis(triphenylphosphine)palladium(0) and 1,2-bis(diphenylphosphino)ethane, α,β-epoxyketones isomerize to the corresponding β-diketones in high yields. Both open-chain and cyclic substrates can be used. Possible reaction mechanisms are discussed.

A synthesis of 2-thiocyanato-2-ethylenic carbonylcompounds was achieved by the reaction of epoxy ketones with Ph3P(SCN)2 (TPPT). Some useful transformations of 2-thiocyanato-2-cyclohexenone to 2,3-disubstituted cyclohexanones and iminothiazolines are described.
