Various unsaturated peroxidic compounds have been prepared, characterized and inductively decomposed in various solvents to afford the corresponding oxiranes. The reaction proceeded by a radical chain mechanism and was initiated either by thermolysis of added t-butyl peracetate at 110°C or AIBN at 80°C, or by autoxidation of BEt₃ at 20°C. The studied peroxyderivatives were designed to generate oxyl radicals reacting either by isomerization (e.g. intramolecular 1,5-hydrogen atom transfer, cyclization or β-scission of a cyclic structure), fragmentation or hydrogen atom transfer to solvents to yield functional alkyl radicals.
