various biarylcarboxylic acids via photoredox catalysis. Attractive features of this process include generation of acyl radical, which quickly underdone intramolecular radical cyclization. This method marks the first photocatalytic intramolecular acyl radical coupling for constructing carbon–carbon bond, which further synthesizes the valuable fluorenone products with mild conditions, good yields, and
已经报道了通过光氧化还原催化通过使用各种联芳基羧酸来合成芴酮的有效的脱氧自由基环化反应。该方法的吸引人的特征包括酰基基团的产生,其迅速完成了分子内基团的环化。该方法标志着首次用于构建碳-碳键的光催化分子内酰基自由基偶联,该偶联进一步合成了温和的条件,良好的收率和良好的官能团相容性的有价值的芴酮产品。
