It remains challenging to achieve valuable platform chems. from lignin because of its complicated polymeric structure and inherent inert chem. activities. So far, only a few examples have been reported for the selective cleavage of C-C bonds in lignin due to their intrinsic inertness and ubiquity. Here, we present a simple and com. available cerium(III) chloride (CeCl3)-promoted photocatalytic depolymerization strategy to realize the simultaneous cleavage and amination of Cα-Cβ bond in a variety of lignin model compounds at room temperature This procedure does not require any pretreatments and breakdown of C-O bonds or loss of γ-CH2OH group to generate aldehydes (up to 97%) and N-containing products (up to 95%) in good to excellent yields. Addnl., this CeCl3-based photocatalyst system could maintain excellent catalytic performance even after 10 sequential cycles with new starting materials. Moreover, this approach realizes the precise control over the reaction via switching the external light stimuli on/off. Further, this method is effective for the depolymerization of real lignin, thus affording the corresponding cleavage and amination products of Cα-Cβ bonds.
