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
已经制备了各种不饱和的过氧化物,对其进行了表征并在各种溶剂中进行了感应分解,从而提供了相应的环氧乙烷。该反应通过自由基链机理进行,并且通过添加的过乙酸叔丁基酯在110℃或AIBN在80℃下热解或在20℃下BEt 3的自氧化来引发。所研究的过氧衍生物被设计为产生羟基,该羟基通过异构化反应(例如分子内1,5-氢原子转移,环状结构的环化或β断裂),断裂或氢原子转移至溶剂中而生成官能烷基。
