The Cover picture shows a tandem catalytic process that rapidly separates woody biomass into a narrow stream of lignin‐derived alkylmethoxyphenols and cellulose‐rich carbohydrates under mild conditions. Metal triflates are identified as a novel class of catalysts effective in the extraction of lignin from the lignocellulosic matrix. The lignin fragments can then be disassembled by Pd‐catalyzed hydrogenolysis. The tandem process is flexible, and good aromatic monomer yields (36–48 wt %) can be obtained from different woods. More details can be found in the Communication by Huang et al. on page 3262 in Issue 23, 2016 (DOI: 10.1002/cssc.201601252).
