Methanethiyl radicals (CH3S.) are shown to react with cyclic ethers containing double bonds to give addition and hydrogen abstraction from the allylic positions. The esr spectra of the corresponding radicals have been determined. In some cases radicals arising from a rearrangement (probably 1,4 H-shift) were observed. t-Butoxyl radicals also give abstraction and addition with the same substrates. In
Methanethiyl自由基(CH 3小号。)被示出与含有双键,得到加法和夺氢从烯丙基位置环醚反应。已确定相应自由基的esr光谱。在某些情况下,观察到由于重排(可能发生1,4 H-移位)而产生的自由基。叔丁氧基还可以在相同的底物上进行抽象和加成。在两种情况下,已经确定了六元环自由基的环反转障碍。
