Ruthenium(II) biscarboxylate oxidase catalysis is a powerful tool for the construction of functionalized arenes with molecular oxygen as the green oxidant, but thus far limited to its use in traditional organic solvents. Herein, we report a green procedure for the ruthenium(II) biscarboxylate catalysed C–H‐functionalisation by using biomass‐derived γ‐valerolactone as medium. The oxidase catalysis shows ample scope and proceeds efficiently with oxygen as the sole oxidant. The overal green nature of the this C–H‐activation methodology is reflected by all organic reactants being obtained by natural feedstocks, while the only byproduct being water.

Abstract
Ruthenium(II) biscarboxylate oxidase catalysis is a powerful tool for the construction of functionalized arenes with molecular oxygen as the green oxidant, but thus far limited to its use in traditional organic solvents. Herein, we report a green procedure for the ruthenium(II) biscarboxylate catalysed C–H‐functionalisation by using biomass‐derived γ‐valerolactone as medium. The oxidase catalysis shows ample scope and proceeds efficiently with oxygen as the sole oxidant. The overal green nature of the this C–H‐activation methodology is reflected by all organic reactants being obtained by natural feedstocks, while the only byproduct being water.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
