Based on the need for green synthesis, photocatalytic oxidation reactions under ambient conditions are vitally significant. Herein, we developed six new quinolinium-grafted polyoxometalate (Q-POM) structures and explored their ability in aerobic of benzyl alcohol-like compounds. Among them, (Bu4N)2+{AlMo6O18[(OCH2)3CCH3][(OCH2)3CNHCOCH2C9H7N]}2– (TBA-Q-Al) can achieve one-step various alcohols to corresponding benzoic acid compounds with favorable yields blue light irradiation at 420–430 nm accompanied by oxygen as sole oxidant. The photocatalyst combines quinolinium π–π conjugation respond property POM backbone storage-transfer electrons. This work provides guidance subsequent development more efficient conversions.

Literature review: state-of-the-art hydrogen storage technologies and Liquid Organic Hydrogen Carrier (LOHC) development

Science and Technology for Energy Transition, Год журнала: 2023, Номер 78, С. 32 - 32

Опубликована: Янв. 1, 2023

Greenhouse gas anthropogenic emissions have triggered global warming with increasingly alarming consequences, motivating the development of carbon-free energy systems. Hydrogen is proposed as an environmentally benign vector to implement this strategy, but safe and efficient large-scale hydrogen storage technologies are still lacking develop a competitive economy. LOHC (Liquid Organic Carrier) improves handling by covalently binding it liquid organic framework through catalytic exothermic hydrogenation endothermic dehydrogenation reactions. LOHCs oil-like materials that compatible current oil infrastructures. Nevertheless, their high enthalpy, platinoid-based catalysts, thermal stability bottlenecks emergence technology. In review, in particular presented. Moreover, potential reactivities design innovative discussed.

Selective Modular Synthesis of ortho-Substituted Phenols via Pd-Catalyzed Dehydrogenation–Coupling–Aromatization of Alcohols

ACS Catalysis, Год журнала: 2023, Номер 13(9), С. 6222 - 6229

Опубликована: Апрель 21, 2023

Phenols are pivotal precursors and core motifs for various fine chemicals, bioactive molecules, functional materials, among which the site-selective syntheses of ortho-substituted phenols very attractive challenging. Here, we present a palladium-catalyzed dehydrogenation–coupling–aromatization protocol to access from cyclohexanols with primary alcohols. Broad substrate scope was achieved in this modular water hydrogen gas as clean byproducts. The ortho-mono- ortho-disubstitutions were readily controlled by N-heterocyclic carbene (NHC) ligands amount base.
