Homogeneous Catalyzed Direct Conversion of Furfural to Gamma‐Valerolactone

Herein, we report the direct conversion of biomass‐derived furfural to γ‐valerolactone (GVL) in a one‐pot system, using the combination of Ru‐MACHO‐BH and a Brønsted acid (H3PO4). A GVL yield of 84 % is achieved under mild reaction conditions using 1 mol% of Ru‐MACHO‐BH and 3.8 M H3PO4(aq) at 100 °C...

Description
Summary:Herein, we report the direct conversion of biomass‐derived furfural to γ‐valerolactone (GVL) in a one‐pot system, using the combination of Ru‐MACHO‐BH and a Brønsted acid (H3PO4). A GVL yield of 84 % is achieved under mild reaction conditions using 1 mol% of Ru‐MACHO‐BH and 3.8 M H3PO4(aq) at 100 °C for 7 hours. We illustrate a sustainable and mild reaction process that efficiently transforms biomass‐derived furfural directly into GVL. Combining the homogeneous catalyst Ru‐MACHO‐BH with H3PO4(aq) allows to transform furfural to GVL in 84 % yield at 100 °C. This demonstrates the feasibility of transforming a major polysaccharide component in lignocellulose (hemicellulose) to GVL in a one‐pot direct approach without intermediate purification and isolation.
