Immobilisation of ketone catalyst: a method to prevent ketone catalyst from decomposing during dioxirane-mediated epoxidation of alkenes

Abstract

Covalent attachment of trifluoromethyl ketone catalyst to a solid support such as silica gel increased the stability of catalyst dramatically, so solving an intrinsic problem of dioxirane-mediated epoxidation of alkenes catalysed by ketones.
