  摘要：

  烯丙基叔丁基过氧化物在环己烷和四氢呋喃中热解的产物分析表明，过氧化物的重要诱导分解是通过将源自溶剂的自由基添加到过氧化物双键中，然后将t的分子内均质置换而完成的。 -丁氧基。该反应是引发剂分解的溶剂的2，3-环氧丙烷化。通过使用其他醚和环烷烃作为溶剂，表明该反应是一般的。

  Free radical additions of hydrogen donor solvents to tert-butyl perpent-4-enoate have given 4-substituted γ-butyrolactones, with yields of 50 % 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
