The selective cleavage of C−O bonds in typical model lignin β‐ O ‐4 compounds and deconstruction of a realistic lignin feedstock catalyzed by Re 2 O 7 is described. High yields of C−O cleavage products (up to 97.8 %) from model compounds and oils (76.3 %) from organosolv pinewood lignin were obtained under mild conditions. Evidence for the pathway of this catalytic process is also provided.
