Wang, Yinling published the artcileRedox-neutral photocatalytic strategy for selective C-C bond cleavage of lignin and lignin models via PCET process, Recommanded Product: 2-Phenoxy-1-phenylpropane-1,3-diol, the publication is Science Bulletin (2019), 64(22), 1658-1666, database is CAplus.
A redox-neutral photocatalytic strategy to accomplish this goal in both β-O-4 and β-1 lignin models at room temperature (RT) via proton-coupled electron transfer (PCET) process without any pretreatments of substrate, by adjusting the alkalinity of base to obtain a lignin models/base PCET pair with a bond dissociation free energy close to 102 kcal/mol was developed. Without breaking down Cβ-Cγ bond and any C-O bonds, this PCET method is 100% atom economy and produces exclusive Cα-Cβ bond cleavage products, such as benzaldehydes (up to 97%) and Ph ethers (up to 96%), in high to excellent yields and selectivities. Preliminary studies indicated that the PCET strategy was also effective for the depolymerization of native lignin at RT, thus providing significantly important foundation to the depolymerization of lignin.
