This review presents the conversion routes, processing strategies, state-of-the-art technical advances, challenges and perspectives in hydrothermal amination of N -rich biomass sources -free feedstocks to nitrogenous chemicals.
This review outlines recent progress in the photocatalytic conversion of biomass into organic acids with an emphasis on mechanisms involved and strategies for rational design/regulation systems to enhance performance.
The synergy between C β –H⋯C (TPP) interaction and oxygen-active species enhances oxidative α –C bond cleavage of lignin β-1/β-O-4 alcohol/ketone models to exclusively afford aromatic acids.
Perinatal depression is common worldwide, which can cause many adverse effects on the physical and mental health of mother baby, as well whole family. The Edinburgh Postnatal Depression Scale (EPDS) an efficient effective instrument for perinatal depression. However, few studies have examined its longitudinal measurement invariance (LMI) during period, particularly important in studies, such exploring developmental trajectories evaluating certain interventions. 4139 pregnant women from 24...
γ-Valerolactone (GVL) has great application potential in organic synthesis and biofuels, while its high-efficiency production from easily available bio-based feedstock is challenging. In this work, SO3H-functionalized P-O-Hf hybrid catalysts GPCS-Hf(n:m) were facilely prepared by solvothermal treatment of glucose-containing precursors (GPC) Hf4+ a mass ratio n:m. The acid strength Lewis/Brønsted sites could be modulated tuning the GPC/Hf4+ ratio. Among them, GPCS-Hf(1:1.5) with appropriate...
Abstract Lactams are privileged in bioactive natural products and pharmaceutical agents widely featured functional materials. This study presents a novel versatile approach to the direct synthesis of lactams from oxocarboxylic acids without catalyst or external hydrogen. The method involves situ release formic acid formamides induced by water facilitate efficient cycloamination. Water also suppresses formation byproducts. unconventional pathway is elucidated combination model experiments...
ZrOCl<sub>2</sub>·8H<sub>2</sub>O exhibited high activity in tandem synthesis of γ-valerolactone and the residual solid after reactions showed remarkable catalytic performance transfer hydrogenation.
Chemocatalytic upgrading of the greenhouse gas CO2 to valuable chemicals and biofuels has attracted broad attention in recent years. Among reported approaches, N-formylation with an amine is great significance due its versatility construction N-containing linear cyclic skeletons. Herein, a stable N-heterocyclic carbene-carboxyl adduct (NHC-CO2) was facilely prepared could be used as recyclable zwitterionic catalyst for efficient reductive via either or further coupling cyclization under mild...
Levulinic acid (LA) and formic (FA) are concurrently derivable from biomass sugars, recognized as sustainable feedstock for producing biofuels chemicals. Herein, a benign eco-friendly approach using low-cost formamide (FAM) FA nitrogen hydrogen source, respectively, was developed to be highly efficient the synthesis of 5-methyl-2-pyrrolidone (MPLD, up 93% yield) LA under quasi-catalytic solvent-free conditions in relatively short reaction time 90 min at 160 °C. Deuterium-labeled control...
A catalyst-free formylation protocol developed herein is efficient for reductive upgrading of CO<sub>2</sub> to formic acid and N-containing benzoheterocyclics, in which endogenous X–CO species play a crucial role the overall reaction processes.
