Synthesis and characterization of compounds fluctuating via radical cleavage and recombination of the carbon-carbon bond.

为了探索在复合和键断裂之间呈现动态相互转化的新的双自由基物种，设计、制备和表征了可能的前体化合物。其中，一种螺环己二酮化合物被发现通过双自由基中间体进行了不寻常的光诱导重排。在一些亚氨基-烯胺类化合物和丙二烯氧基自由基前驱体中发现了质子的动态迁移。

With the intention of exploring new diradical species which show dynamic interconversion between recombination and bond cleavage, possible precursor compounds were designed, prepared and characterized. Among those, a spiro-cyclohexadienone compound was found to undergo unusual photoinduced rearrangements via a diradical intermediate. Dynamic proton migration was found in some imino-enamine compounds and in precursor compound for galvinoxyl radicals.
