The selective cleavage of C-O bonds in typical model lignin β-O-4 compounds and deconstruction of a realistic lignin feedstock catalyzed by Re O is described. High yields of C-O cleavage products (up to 97.8 %) from model compounds and oils (76.3 %) from organosolv pinewood lignin were obtained under mild conditions. Evidence for the pathway of this catalytic process is also provided.
描述了由ReO催化的典型模型木质素β-O-4化合物中C-O键的选择性裂解以及实际木质素原料的解构。在温和条件下，模型化合物的C-O裂解产物收率很高（高达97.8%），有机溶剂法松木木质素的油收率为76.3%。还提供了该催化过程途径的证据。
