methodology is compatible with a wide variety of diversely substituted 1,4-naphthoquinones as well as various cheap, readily available benzyl bromides with excellent functional group tolerance. The benzylation mechanism was investigated and supports a three-step radical cascade with the key involvement of the photogenerated superoxide anion radical.
在 Fe(III)、氧和 γ-萜品烯作为氢原子转移剂的存在下,通过使用蓝光诱导的光氧化还原过程以良好的收率获得了 3-Benzylmenadiones。该方法与各种不同取代的 1,4-萘醌以及各种廉价、易于获得的具有优异官能团耐受性的苄基溴兼容。研究了苄基化机制,并支持光生超氧阴离子自由基参与的三步自由基级联反应。
