Thermolyses of dicyclohexyl carbonyl peroxide have been performed in organic solutions of t-butyl pent-4-enyl peroxide or t-butyl perpent-4-enoate in order to study the induced decomposition by cyclohexyl radicals of these peroxides.Induced decomposition of cyclohexylcarbonyl pent-4-enoyl peroxide and pent-4-enyl cyclohexylpercarboxylate has also been studied.In the decomposition of these compounds, SHi reaction of an acyloxy radical is involved which is, to our knowledge, the first example of such reaction with a perester.

Free radical additions of hydrogen donor solvents to tert-butyl perpent-4-enoate have given 4-substituted γ-butyrolactones, with yields of 50 percent or greater.Such reactions applied to allyl-tert-butyl peroxide have produced 2,3-epoxypropanation of these solvents.Similar addition-elimination processes occurred with tert-butyl 4-methyl-perpent-4-enoate, tert-butyl 2,2-dimethyl-perpent-4-enoate and tert-butyl-methallyl peroxide, but they failed with tert-butyl 5-methyl-perhex-4-enoate and tert-butyl-3-methyl-but-2-enyl peroxide.
