Methanol is a fundamental feedstock and widely used in the chemical petroleum industries. It can serve as C1 source to make variety of C–C C–N bond formation dehydrogenative coupling products, which have important applications natural products drug discovery. A high hydrogen content (12.5 wt%) methanol makes it an effective H2 donor for transfer hydrogenation various reducible functional groups. plethora transition metal-based processes been developed using methanol. Notably, recent review articles focused on aspect However, more updated that examines challenges both C1-source H2-source organic transformations contributing concept economy has not presented yet. This Review summarizes (homogeneous, heterogeneous, photo-) catalyst system C-, N-, O-methylation ketones, alcohols, amides, nitriles, heterocyclic compounds, sulfones, amines, sulfonamides direct N-methylation nitro compounds under borrowing strategy N-formylation amines acceptorless dehydrogenation source. also covers insights into reaction mechanisms role carefully selected ligands metal catalysis activation incorporation -CD3, methylation molecules. Moreover, describes groups such aldehydes, alkynes, with detail.

Bimetallic Porphyrin Metal–Organic Framework as Photocatalyst for Red-Light-Driven Selective Reduction of Nitroarenes to Aromatic Amines

ACS Sustainable Chemistry & Engineering, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 28, 2024

It is a great challenge to construct green catalytic system for the reduction of nitro compounds corresponding amines under mild conditions. Due low energy red light, it challenging develop photocatalytic selective nitroaromatics aromatic driven by light. A bimetallic porphyrin metal–organic framework (Bi-P(Co)MOF) was characterized Fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy, scanning and energy-dispersive techniques. The constructed photocatalyst Bi-PMOF-Co shows excellent activity conversion in high yields with NaBH4 as reducing agent at room temperature light irradiation. Moreover, protocol showed functional group compatibility, recyclability demonstrated five-cycle tests.

SnO_x-Decorated Pt Catalysts for the Reductive N-Methylation of Quinoline with Methanol

ACS Sustainable Chemistry & Engineering, Год журнала: 2024, Номер 12(19), С. 7644 - 7654

Опубликована: Апрель 30, 2024

A direct and efficient synthesis of N-methyl-1,2,3,4-tetrahydroquinolines (MTHQs) is achieved through the one-pot reductive N-methylation quinolines. The SnOx-decorated Pt/Al2O3 (Pt-SnOx/Al2O3) catalyst proves to be highly effective in transformation from quinolines MTHQs, using methanol as exclusive source for hydrogen (H) methyl (CH3), without addition additional bases or additives. Mechanistic kinetic studies reveal a tandem reaction pathway: (1) dehydrogenation methanol, (2) reduction 1,2,3,4-tetrahydroquinolines (THQs), (3) THQs with identified rate-determining step. Characterization catalytic performance results demonstrate that SnOx modifies morphology electronic properties Pt-based metal active sites, which dramatically facilitates cleavage O–H less reactive C–H bonds maintains delicate balance between quinolines, thus obtaining high reactivity total transformation.
