✦ Synopsis

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-but~-I 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 reactmg either by isomerization (e.g. intramolecular 1,5-hydrogen atom transfer, cyclization or 13-scission of a cyclic structure). fragmentation or hydrogen atom transfer to solvents to yield functional alkyl radicals.
