Solvent Effects on Heterogeneous Catalysis for the Selective Hydrogenation

ChemCatChem, Journal Year: 2024, Volume and Issue: 16(14)

Published: April 1, 2024

Abstract Solvent effects add a new dimension for tuning the activity and selectivity of heterogeneous catalytic reactions, which is extensively employed in hydrogenation unsaturated compounds with multiple functional groups. In this concept, we briefly summarize recent developments on how solvent affect performance from following aspects: 1) polarity can influence interaction between reactant or intermediate; 2) composition mixed reactivity 3) effect varies metal identity support; 4) induce surface modification supported catalysts. This summarization will provide insights into rational development efficient selective system to realize precise synthesis desired chemicals.

Published: March 15, 2025

Abstract Developing an efficient catalyst for converting furan alcohols to cyclopentenones fine chemical synthesis is crucial but challenging due the easy overhydrogenation side reactions tetrahydrofuran and cyclopentanones. This study demonstrates that cobalt disulfide (CoS 2 ) exhibits unprecedented yield of 80.1% during rearrangement–hydrodeoxygenation alcohol cyclopentenone. CoS acts not only as Lewis acid sites rearrangement step also adjustable H activation CC hydrogenation 4‐hydroxy‐2‐cyclopentenone intermediates, promoting Furthermore, it exhibits, first time, a similar route toward 3‐methyl cyclopentenone from 5‐methyl 2,5‐dihydroxymethyl furan.

Kinetics and mechanistic insights into hydrogenative rearrangement of hydroxymethylfurfural over acid‐Nickel catalysts

AIChE Journal, Journal Year: 2025, Volume and Issue: unknown

Published: April 8, 2025

Abstract Catalytic hydrogenative rearrangement of furanic aldehydes is crucial for producing biomass‐derived cyclopentanone fine chemicals. However, designing highly selective catalysts remains challenging due to the interplay among tandem hydrogenation, ring‐opening, aldol condensation, dehydration, and parallel ring‐hydrogenation. Here, we employ a single self‐assembly step by depositing phosphonic acids (PAs) on conventional Ni introduce tunable interfacial Brønsted acid sites (BAS), resulting in an unprecedented 3‐hydroxymethyl‐cyclopentanone yield 95.8% from hydroxymethylfurfural. Kinetic studies reveal one‐order‐of‐magnitude increase ring‐opening rates—the slow rearrangement—after PAs modification, accompanied drop apparent activation energy 154.1 105.4 kJ mol −1 . In contrast, ring‐hydrogenation side reaction almost unchanged. Theoretical calculations suggest that BAS synergize with adjacent lower C–O cleavage barrier providing protons attack hydroxymethyl oxygen atom, which key initiate ring‐opening.
