Epoxidation of 2-Butene-1,4-diones with Hydrogen Peroxide in the Presence of a Catalytic Amount of Quaternary Ammonium Iodide
The epoxidation of 1,4-disubstituted 2-butene-1,4-diones with 30percent aq.H2O2 in the presence of a catalytic amount of quaternary ammonium iodide afforded 2,3-epoxy-1,4-butanediones in high yield.

Photosensitized Oxidation of Furans. Part 7. Solvent Effects in Thermal Conversion of the endo-Peroxides of Arylfurans
Thermal conversion of the endo-peroxides of the arylfurans (1) in a polar aprotic solvent leads to aroylenol esters (4) and diaroyl epoxides (3), the predominance of one over being concentration dependent.The results can be rationalized on the basis of th
