blocks in organic synthesis. By utilizing CBZ6, with an oxidative potential of −2.16 V (vs the saturated calomel electrode), as a redox-neutral photocatalyst, alkoxyacylation of olefins was accomplished under the irradiation of visible light via a cationic intermediate. It involves the addition of an acyl radical to olefin to form a radical intermediate and the following oxidation of the radical intermediate
β-烷氧基酮是有机合成中的重要组成部分。利用氧化电位为-2.16 V(相对于饱和甘汞电极)的CBZ6作为氧化还原中性光催化剂,在可见光照射下通过阳离子中间体完成烯烃的烷氧基酰化。它涉及将酰基自由基加成到烯烃上以形成自由基中间体,然后将自由基中间体氧化成被烷氧基阴离子捕获的苄基阳离子中间体。该过程提供了简洁且实用的β-官能化酮的制备方法。
