However, most methods within this class of reactions makes use of reprotoxic, amide-based solvents. Mechanochemistry, a method that does not always require solvent, has been used for reductive coupling methods but still reports the use of at least some amide-based solvent for productive outcomes. This work presents the reactivity trends for the reductive homocoupling of aryl iodides when using various amounts of N,N-dimethylformamide (a commonly used amide-based solvent) and dimethyl carbonate (a greener alternative). The results of these experiments show that dimethyl carbonate may be used in sub-stoichiometric amounts with equal or greater efficiency to N,N-dimethyl formamide. Further, cross-electrophile coupling (XEC) is explored with various solvents, showing that N-butyl pyrrolidinone is efficient as a liquid assisted grinding solvent. These experiments show that under mechanochemical conditions, safer solvents are able to be used with no loss of efficacy for reductive coupling reactions.

However, most of these processes are under pressures significantly higher than atmospheric level, which not only levies additional equipment and operation costs, but also makes the large-scale CO2 capture and conversion less practical. In this study, we rationally designed glycol ether-functionalized imidazolium, phosphonium and ammonium ILs containing acetate (OAc-) or Tf2N- anions, and found these task-specific ILs could solubilize up to 0.55 mol CO2 per mole of IL (or 5.9 wt% CO2) at room temperature and atmospheric pressure. Although acetate anions enabled a better capture of CO2, Tf2N- anions are more compatible with alcohol dehydrogenase (ADH), which is a key enzyme involved in the cascade enzymatic conversion of CO2 to methanol. Our promising results indicate the possibility of CO2 capture under ambient pressure and its enzymatic conversion to valuable commodity.","PeriodicalId":12768,"journal":{"name":"Green Chemistry Letters and Reviews","volume":"16 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10254919/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9629314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research seeks to develop highly functionalized textile-based sensors, actuators, and energy storage devices that integrate seamlessly with current textile technologies. Presently, developments are limited by either low electrical performance, or high cost and complex construction. Additionally, negotiating the balance between high performing e-textiles and environmentally benign production is a challenge. In this report, green synthesized silver nanoparticles (AgNPs) are composited with the conjugated polymer, polypyrrole (Ppy), to create a low-cost conductive textile fabric. A Plackett–Burman design of experiment was used to optimize lime peel extract (LPE) mediated reduction for the synthesis of AgNPs. The results of this optimization process revealed silver nitrate concentration to be a significant factor in both size and UV-vis absorption maxima of the LPE-synthesized AgNPs, and reaction temperature also affecting UV-vis absorption maxima. The resultant optimized AgNPs were consistent in size (40–80 nm) and dispersity (PDI = 0.250). The LPE-synthesized AgNPs are used to form a AgNP-Ppy nanocomposite with a linen textile to produce an e-textile with low electrical resistance (37 Ω).

One example is the need for safer, bio-derived solvents to replace those currently in use for the polymer’s synthesis and processing. In this work, several variants of the bio-based cellulose/levoglucosenone derived solvent Cyrene, namely the ketal derivatives dioxolane Cygnet, dioxane Cygnet and dioxepane Cygnet were synthesized and tested as media for enzymatic polycondensation reactions using bio-based building blocks. Dioxolane Cygnet and dioxepane Cygnet were found to be suitable solvents for enzymatic polycondensation reactions, with dioxolane Cygnet being the preferred solvent, yielding polymers with a Mn >22 kDa. In addition, these solvents were tested in the biocatalyzed synthesis of levoglucosenone-based polyesters. The alternative solvents gave superior yields to those previously observed, demonstrating the versatility of these solvents in enzymatic polycondensation reactions, representing the first synthetic polymer-solvent system fully derived from cellulose.

In this study, novel triazole-based azomethine/thiazolidin-4-one hybrid analogs were designed, prepared and structurally confirmed by using elemental and spectral techniques, these include FT-IR, MS, and NMR spectra. In addition, in vitro cytotoxic activity was assessed against NCI-60 cancer cell lines. To understand the possible mode of action and drugability, molecular docking studies and drug-likeness were achieved. The docking simulations were performed against various Rab family proteins Rab2a, Rab25, Rab5, and Rab35; promising targets for cancer medication to support the cytotoxicity findings and to further validate the action of new molecules. Furthermore, in silico ADMET screening of the molecules was within the recommended values stated by Lipinski's rule of five (Ro5), indicating their oral bioavailability and therapeutic potentials. Among the newly prepared analogs tested, compounds 4d and 3d exhibited significant antitumor activity against breast, ovarian, lung, and leukemia cancer cell lines. Our findings suggested that azomethine/thiazolidin-4-one moieties incorporated triazole analogs are a promising class of molecular entities for the development of new anticancer therapies, through targeting of some Rab proteins.

Transition-metal-catalyzed C–H bond functionalization needs metal catalysts such as palladium, rhodium, iridium, cobalt, copper, etc., which is not conducive to its sustainable development. In recent years, C(sp3)-H bond functionalization without transition metal catalyst has been studied increasingly. In the meantime, electrochemistry has become one of the most dynamic research fields in organic synthesis for the reason that it can substitute the traditional expensive and polluting metal salt oxidants (e.g. Cu2+, Ag+ salt) with current/electrons to act as a redox agent. So the applications of electrochemistry combined with transition-metal-free C(sp3)-H bond functionalization to solve some long-standing challenges have gradually gotten more and more attention in recent years. In this review, the researches on transition-metal-free electrochemical-induced C(sp3)-H bond functionalization from 2016 to now will be systematically presented and the future research hotspots and difficulties in this field will also be prospected.
