Ruthenium(II) biscarboxylate oxidase catalysis is a powerful tool for the assembly of functionalized arenes with oxygen as a green oxidant, but this strategy was thus far limited to its use in traditional organic solvents. Herein, we report on a green procedure for the ruthenium(II) biscarboxylate-catalysed C–H functionalisation in biomass-derived γ-valerolactone as the reaction medium. The oxidase catalysis was characterized by ample substrate scope and proceeded efficiently with oxygen as the sole oxidant. The overall green nature of this C–H-activation methodology is reflected by H₂O being the only by-product.

钌（II）氧化酶催化生物质衍生的γ-戊内酯中的CH烯基化

钌（II）双羧酸盐氧化酶催化是用氧气作为绿色氧化剂组装官能化芳烃的强大工具，但该策略迄今仅限于其在传统有机溶剂中的使用。在本文中，我们报道了在生物质衍生的γ-戊内酯作为反应介质中，钌（II）双羧酸双酯催化的C–H功能化的绿色过程。氧化酶催化的特征是具有足够的底物范围，并且以氧气作为唯一氧化剂可以有效地进行。H ₂ O是唯一的副产物，反映了这种C–H活化方法的整体绿色性质。
