The regioselective outcome observed during dimerisation of butenolides to dimeric structures via captodative stabilised radicaloids has been studied. The captodative stabilised radicaloids were generated by initial conversion of butenolides to chlorobutenolides via the corresponding hydroxybutenolides, followed by treatment with CoCl(PPh3)3.
研究了在丁烯内酯通过capdodative稳定的基团二聚化为二聚体结构过程中观察到的区域选择性结果。通过将丁烯内酯通过相应的羟基丁烯内酯初步转化为氯丁烯内酯,然后用CoCl(PPh 3)3处理,生成了具有captodative稳定性的自由基。
