their heteroatom analogues were conveniently synthesized from the reaction of chromones and their heteroatom analogues with CF3SO2Na or HCF2SO2Na in the presence of tert-butyl hydroperoxide under mild conditions. A mechanistic pathway involving the generation of the electrophilic tri/difluoromethyl radical, followed with the radical substitution of chromones and their heteroatom analogues, was postulated
在叔丁基过氧化氢存在下,在温和条件下,通过色酮及其杂原子类似物与CF 3 SO 2 Na或HCF 2 SO 2 Na的反应,方便地合成了一系列具有生物学意义的三/二氟甲基化色酮及其杂原子类似物。假设了一种机械途径,涉及亲电子三/二氟甲基自由基的产生,然后是色酮及其杂原子类似物的自由基取代。
