- W1981504342 abstract "Cyclohexene and 1-octene have been epoxidized with tert-butyl hydroperoxide at 80 °C, in the presence of several boron esters. The catalytic activities of the boron compounds are markedly dependent on their structures and are enhanced by the presence of electron-attracting substituents, which increase the electrophilicity of the boron atom. Alkyl and aryl metaborates catalyze the epoxidation but are rapidly deactivated via alcoholysis to give the corresponding orthoborates, which are inactive. Orthoborate esters containing sufficiently strong electron-withdrawing groups (such as acetylacetonate or hexafluoroacetylacetonate) are, on the other hand, active catalysts. They are also deactivated during the reaction via alcoholysis and/or oxidative destruction of the ligands by hydroperoxide." @default.
