| 英文摘要 | The catalysts with well-defined mononuclear active sites are expected to develop more active catalytic systems for the key chemical transformations. But the rational design of catalyst with stable mononuclear Mo site is still a crucial challenge because of its oligomerization tendency under reaction condition. Herein, Molybdenum catalyst (Mo-8-HQ) with single Mo sites was designed via the pyridine nitrogen and oxygen in hydroxyl of 8-hydroxyquinoline coordinated with Mo atom. The crystal catalyst was stabilized by pi-pi stacking interaction and hydrogen bonds to form isolated Mo specie. The single-site molybdenum catalyst exhibited excellent catalytic performance in didehydroxylation reactions with high selectively of dibutyl fumarate (86 %) product at mild reaction condition. Deuterium isotopic studies demonstrated that the mechanism feature of didehydroxylation reaction catalyzed by Mo-8-HQ was through concerted cleavage of two C-O bonds process, which could be accelerated by single-site molybdenum catalysts with electron-rich Mo centers. |
