the first radical C(sp3)–H Heck-type reaction of aliphatic alcohols for selective δ- and ε-alkenol synthesis by photoredox catalysis. N-Alkoxybenzimidoyl chlorides are developed as novel alkoxyl radical precursors with tunable redox potentials. Various alkenols can be constructed by the inert C(sp3)–H Heck-type reaction of 4-cyano-N-alkoxybenzimidoyl chlorides with styrene derivatives under redox-neutral
我们报告了脂肪醇的第一个自由基 C(sp 3 )-H Heck 型反应,用于通过光氧化还原催化选择性合成 δ-和 ε-烯醇。N-烷氧基苯并亚胺酰氯被开发为具有可调氧化还原电位的新型烷氧基自由基前体。在氧化还原中性条件下,4-氰基-N-烷氧基苯并亚氨基酰氯与苯乙烯衍生物发生惰性 C(sp 3 )-H Heck 型反应可以构建各种烯醇,该反应可以在克级规模上进行,并且易于衍生化.
