Next-generation techniques for sustainable carboxylate production generate salts as the primary outcome. To circumvent costly conversion of to acids, we demonstrate aqueous (non-)Kolbe electrolysis process an alternative strategy downstream value-added chemicals. Upon revealing irreversible oxidation-induced charge transfer inhibition on graphite anode, propose anion intercalation mitigate stability problem induced by ever-increasing overpotential. In acetate decarboxylation, observe a high Faradaic efficiency ~95% non-Kolbe products (methanol and methyl acetate) at wide current densities ranging from 0.05 1 A cm-2 long-term 0.15 0.6 130 35 h, respectively. We also extended this upgrading long-chain carboxylates such propionate, butyrate, succinate. Our work provides valuable guidance extendable overcoming passivation challenges in catalysis.

Phytosterol organic acid esters are important food resources and the components of biomembrane structure. Due to lack extraction synthesis techniques, more research has been focused on phytosterols, phytosterol have encountered a bottleneck, but confer substantial benefits human health. In this study, stigmasteryl vanillate (VAN), protocatechuate (PRO) sinapate (SIN) were prepared through Steglich reaction. The processes promotable products reach up 95% purity. addition, their stability was evaluated by differential scanning calorimetry thermogravimetric analysis. HPLC analysis revealed an enhancement in water solubility after esterification with phenolic acid. vitro digestion model, bioaccessibility phenolates significantly higher than that stigmasterols (STIs). Regarding anti-inflammatory properties, VAN, PRO, SIN exhibit superior effects against TNF-α induced pro-inflammatory responses compared STI. All supplementation increased ATP production, basal, maximal oxygen consumption rate mitochondrial stress test. Overall, we present method for phenolates. It will contribute development ester analysis, functions utilization food. Moreover, nutrient-stigmasterol hybrids tactic constructed is practical can become targeted delivery strategy enhanced effects.

Abstract Carboxylic acids are attractive synthetic feedstocks with stable, non‐toxic, and inexpensive properties that can be easily obtained from natural sources or through synthesis. have long been considered environmentally friendly coupling agents in various organic transformations. In recent years, electrochemically mediated decarboxylation reactions of decarboxylic their derivatives (NHPI) emerged as effective new methods for constructing carbon‐carbon carbon‐heterocarbon chemical bonds. Compared transition metal photochemistry‐mediated catalytic reactions, which do not require the addition oxidants strong bases, electrochemically‐mediated decarboxylative transformations a sustainable strategy. addition, functional groups tolerate electrochemical conversion strategy well. Here, we summarize to better elucidate advantages reactions.
