in the ligand structure divert the reactivity of vanadium(V) oxo complexes from alcohol oxidation to a novel non‐oxidative CO bond cleavage. Thus, highly functionalized aryl enones can be selectively generated from lignin model compounds by vanadium‐catalyzed cleavage of the β‐O‐4 linkage (see scheme; N blue, O red).
新方向:配体结构的变化将钒(V)氧配合物的反应性从醇氧化转移到新型非氧化性C - O键断裂。因此,通过钒催化的 β-O-4 键断裂,可以从木质素模型化合物中选择性地生成高度官能化的芳基烯酮(参见方案;N 蓝色,O 红色)。
