A new method for the formation of γ- and δ-lactones from carboxylic acids through direct conversion of benzylic C-H to C-O bonds is described. The reaction is conveniently induced by visible light and relies on a mild cooperative catalysis by the combination of molecular iodine and an organic dye.
本文描述了一种从羧酸通过直接转化苄位 C-H 键到 C-O 键形成γ-和δ-内酯的新方法。该反应可通过可见光方便地诱导,并依赖于分子碘和有机染料的组合的温和协同催化。
