The search for nonprecious-metal-based catalysts for the synthesis of γ-valerolactone (GVL) through hydrogenation of levulinic acid and its derivatives in an efficient fashion is of great interest and importance, as GVL is an important a sustainable liquid. We herein report a pincer iron complex that can efficiently catalyze the hydrogenation of levulinic acid and methyl levulinate into GVL, achieving a turnover number of up to 23 000 and a turnover frequency of 1917 h . This iron-based catalyst also enabled the formation of GVL from various biomass-derived carbohydrates in aqueous solution, thus paving a new way toward a renewable chemical industry.
寻找用于通过高效氢化乙酰丙酸及其衍生物来合成γ-戊内酯（GVL）的非贵金属基催化剂具有重大意义且备受关注，因为GVL是一种重要的可持续液体。我们在此报告一种钳形铁配合物，它能够有效地催化乙酰丙酸和乙酰丙酸甲酯氢化为GVL，实现高达23000的转数和1917 h⁻¹的转换频率。这种铁基催化剂还能使水溶液中各种生物质衍生的碳水化合物形成GVL，从而为可再生化学工业开辟了一条新途径。
