Herein, we report the use of a single-atom Co catalyst for the oxidative cleavage of the -O-4 bonds of lignin model compounds at a low oxygen pressure. Under the optimized reaction conditions, the conversion of 2-(2-methoxyphenoxy)-1-phenylethanol up to 95% with high selectivities was achieved with a variety of substrates investigated. The reusability of the Co catalyst with a high catalytic efficiency indicates its potential application in the oxidative cleavage of C-O bonds.Chemistry, MultidisciplinaryGreen & Sustainable Science & TechnologyChemistryScience & Technology - Other Topicsdissociation enthalpiesaerobic oxidationmolecular-oxygendepolymerizationhydrogenationalcoholsreduction2-stepliquidsitesOxidative cleavage of -O-4 bonds in lignin model compounds with a single-atom Co catalysttext::journal::journal article::research article
