Recent efforts focused on the production of selected chemicals from biomass as an effective approach to replace fossil feedstocks. Among them, transformation of the biogenic platform molecule levulinic acid to γ‐valerolactone has been an extensively studied reaction. Although this transformation can be achieved by heterogeneous catalysis, there exists also a strong interest for effective homogeneous catalysis that can operate selectively under milder and sustainable conditions. Herein, we report the utilization of various triphos‐analogue ligands that in the presence of Ru(acac) 3 (acac=acetylacetonate) lead to highly efficient γ‐valerolactone production (yield up to 95 %). Excellent catalyst turnover numbers (up to 75 855) and turnover frequencies (up to 1382 h −1 ) were accomplished.
