摘要：

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 chloro-butenolides via the corresponding hydroxylbutenolides, followed by treatment with CoCl(PPh3)(3).
