A review of fatty epoxide ring opening reactions: Chemistry, recent advances, and applications

Journal of the American Oil Chemists Society, Год журнала: 2022, Номер 99(10), С. 801 - 842

Abstract Fatty epoxides are produced from the corresponding alkenes by oxidation in presence of peracids or other oxidants. The classic method is Prilezhaev epoxidation which generated situ formic acetic acids with hydrogen peroxide. Epoxidized vegetable oils and esters used directly as biobased plasticizers stabilizers for poly(vinyl chloride) important platform chemicals oleochemical industry. Nucleophilic attack at oxirane moiety affords a variety ring opened monomeric polymeric products, many cases undergo further synthetic modification to yield finished products. most common nucleophiles include water, alcohols, carboxylic acids, acid anhydrides, amines, although numerous others can also lead valuable functionalized fatty derivatives. This review summarizes chemistry epoxide opening reactions well applications resultant Literature last 20 years will be emphasized, older publications particular significance included. Important lubricants polyols subsequent production polyurethanes. In addition, ring‐opening hitherto unreported on oxiranes suggested facilitate advancements utility epoxides. Finally, interest their consequent products continue grow due simplicity, efficiency, versatility formation continued societal transition away petroleum sustainable, circular, low‐carbon, economy.

Atomically Dispersed Metal Catalysts for the Conversion of CO₂ into High‐Value C₂₊ Chemicals

Advanced Materials, Год журнала: 2024, Номер 36(37)

Опубликована: Май 19, 2024

Abstract The conversion of carbon dioxide (CO 2 ) into value‐added chemicals with two or more carbons (C 2+ is a promising strategy that cannot only mitigate anthropogenic CO emissions but also reduce the excessive dependence on fossil feedstocks. In recent years, atomically dispersed metal catalysts (ADCs), including single‐atom (SACs), dual‐atom (DACs), and single‐cluster (SCCs), emerged as attractive candidates for fixation reactions due to their unique properties, such maximum utilization active sites, tunable electronic structure, efficient elucidation catalytic mechanism, etc. This review provides an overview significant progress in synthesis characterization ADCs utilized photocatalytic, electrocatalytic, thermocatalytic toward high‐value C compounds. To provide insights designing chemical originating from , key factors influence activity selectivity are highlighted. Finally, relevant challenges opportunities discussed inspire new ideas generation ‐based products over ADCs.

New sustainable concepts have to be developed overcome the increasing problems of resource availability. Cellulose derivatives with tunable material properties are promising biobased alternatives existing petroleum-derived polymeric materials. However, chemical modification cellulose is very challenging, often requiring harsh conditions and complex solubilization or activation steps. More procedures toward novel therefore great interest. Herein, we describe a concept combining two approaches, (i) tandem catalysis (ii) derivatization, by applying single catalyst for three transformations in DMSO/DBU/CO2 switchable solvent system. was functionalized four different isothiocyanates, which were formed situ via catalytic sulfurization isocyanides elemental sulfur, preventing exposure handling isothiocyanates. The degree substitution O-cellulose thiocarbamates shown controllable range 0.52-2.16 varying equivalents reactants. All obtained products analyzed ATR-IR, 1H, 13C, 31P NMR spectroscopy as well size exclusion chromatography, analysis, differential scanning calorimetry, thermal gravimetric analysis. Finally, reaction approach beneficial terms efficiency sustainability compared stepwise synthesis.
