A novel green solvent, γ-valerolactone (GVL), efficiently facilitates the photocatalytic activation of C−H bonds in benzylic compounds. Mechanistic studies reveal that GVL′s high dielectric constant (ϵ) increases the driving force (−ΔG), and its large refractive index (n) reduces reorganization energy (λ), collectively reducing the reaction barrier (ΔG). This research advances the overlooked solvent effects in semiconductor photocatalysis.

绿色溶剂 γ-戊内酯 (GVL) 促进光催化 C-H 键活化



γ-戊内酯 (GVL) 是一种新型绿色溶剂,可有效促进苄基化合物中 C-H 键的光催化活化。机理研究表明,GVL 的高介电常数 (ε) 增加了驱动力 (−ΔG),其大折射率 (n) 降低了重组能 (λ),共同降低了反应势垒 (ΔG)。这项研究推进了半导体光催化中被忽视的溶剂效应。
