homogeneous nickel‐based catalyst using the complex [dippeNi(COD)] (dippe=1,2‐bis(diisopropyl phosphino)ethane) as a catalytic precursor with high activity in the hydrogenation of levulinicacid (LVA) to yield γ‐valerolactone (GVL) under relatively mild conditions (4 h, 120 °C); formic acid (FA) is the transfer hydrogenation agent in a dehydrogenation‐hydrogenation process. Under optimized conditions
