Ruthenium–triphos complexes exhibited unprecedented catalytic activity and selectivity in the redox‐neutral CC bond cleavage of the β‐O‐4 lignin linkage of 1,3‐dilignol model compounds. A mechanistic pathway involving a dehydrogenation‐initiated retro‐aldol reaction for the CC bond cleavage was proposed in line with experimental data and DFT calculations.
