Lang, Simon B. published the artcileActivation of Alcohols with Carbon Dioxide: Intermolecular Allylation of Weakly Acidic Pronucleophiles, COA of Formula: C16H13NO, the main research area is nitroalkane allyl alc carbon dioxide palladium allylation catalyst; nitrile allyl alc carbon dioxide palladium allylation catalyst; aldehyde allyl alc carbon dioxide palladium allylation catalyst; allylated product preparation.

The direct coupling of allyl alcs. with nitroalkanes, nitriles, and aldehydes using catalytic Pd(PPh3)4 has been accomplished via activation of C-OH bonds with CO2. The in situ formation of carbonates from alcs. and CO2 facilitates oxidative addition to Pd to form reactive π-allylpalladium intermediates. In addition, the formation of a strong base activates nucleophiles toward the reaction with the π-allylpalladium electrophile. Overall, this atom economical reaction provides a new C-C bond without the use of an external base and generates water as the only byproduct.

Zhang, Zhengqing;Cao, Xiaohao;Geng, Chenxu;Sun, Yuxiu;He, Yanjing;Qiao, Zhihua;Zhong, Chongli research published 《 Machine learning aided high-throughput prediction of ionic liquid@MOF composites for membrane-based CO₂ capture》, the research content is summarized as follows. Ionic liquid encapsulated metal-organic framework (IL@MOF) composites as promising filler used for mixed matrix membranes (MMMs) fabrication to break the trade-off limitation. However, discovering appropriate IL@MOF composites effectively and cost-efficiently still faces a great challenge. In this study, we first construct the filler database consisting of 8167 IL@MOF composites by inserting [NH₂-Pmim][Tf₂N] mol. into computation-ready, exptl. metal-organic frameworks (CoRE MOFs). Using mol. simulation, we identified the best IL@MOF composites based on different metrics and revealed gas separation mechanism. Working with RF model (R² > 0.72), we uncover that the AV and gASA are key factors in predicting the membrane selectivity and CO₂ permeability, resp. The [NH₂-Pmim][Tf₂N]@ZIF-67 predicted can be as one of candidates for MMMs fabrication. The exptl. results show that CO₂ permeability (9536 Barrer) and CO₂/N₂ selectivity (31.1) of [NH₂-Pmim][Tf₂N]@ZIF-67/PIM-1 have 121.3% (37.6%) and 32.6% (38.8%) enhancements compared with unfilled PIM-1 (ZIF-67/PIM-1), surpassing the updated CO2/N2 Jansen/McKeown upper bound. Our computational study could offer effective prediction and may trigger exptl. efforts to accelerate development of novel IL@MOF composites used for fabricating MMMs with excellent performance.

Zhao, Genfu;Xu, Lufu;Jiang, Jingwen;Mei, Zhiyuan;An, Qi;Lv, Pengpeng;Yang, Xiaofei;Guo, Hong;Sun, Xueliang research published 《 COFs-based electrolyte accelerates the Na⁺ diffusion and restrains dendrite growth in quasi-solid-state organic batteries》, the research content is summarized as follows. Solid-state sodium-ion batteries exhibit a great promising opportunity for the future energy storage, and thus exploring a high-efficiency sodium-ion conductor is the urgent challenge. Covalent organic frameworks (COFs) have accurately directional and well-defined ion channels and are a promising and optimal platform for solid-state Na-ion conductor. In this work, we study the first example of carboxylic acid sodium functionalized polyarylether linked COF (denoted as NaOOC-COF) as an advanced Na-ion quasi-solid-state conductor film. Benefiting from the well-defined ion channels, the functionalized NaOOC-COF exhibits an outstanding Na⁺ conductivity of 2.68 x 10^-4 S cm^-1 at room temperature, low activation energy (Ea) with 0.24 eV and high transference number of 0.9. Particularly, the NaOOC-COF shows long-time cycling performance in the assembled quasi-solid-state battery, and can restrain dendrite growth through interface regulation. Furthermore, the Na⁺ diffusion mechanism in whole-cell system is investigated thoroughly. Such extraordinary Na-ion transport result based on COFs is achieved for the first time. This novel strategy may exploit the new area of Na-ion quasi-solid-state electrolytic devices, and simultaneously accelerate the progress of functionalized COFs.

Zhao, Lu;Zheng, Lu;Li, Xiaopeng;Wang, Han;Lv, Li-Ping;Chen, Shuangqiang;Sun, Weiwei;Wang, Yong research published 《 Cobalt Coordinated Cyano Covalent-Organic Framework for High-Performance Potassium-Organic Batteries》, the research content is summarized as follows. Potassium ion batteries (PIBs) are expected to become the next large-scale energy storage candidates due to its low cost and abundant resources. And the covalent organic framework (COF), with designable periodic organic structure and ability to organize redox active groups predictably, has been considering as the promising organic electrode candidate for PIB. Herein, we report the facile synthesis of the cyano-COF with Co coordination via a facile microwave digestion reaction and its application in the high-energy potassium ion batteries for the first time. The obtained COF-Co material exhibits the enhanced π-π accumulation and abundant defects originated from the Co interaction with the two-dimensional layered sheet structure of COF, which are beneficial for its energy-storage application. Adopted as the inorganic-metal boosted organic electrode for PIBs, the COF-Co with Co coordination can promote the formation of the π-K⁺ interaction, which could lead to the activation of aromatic rings for potassium-ion storage. Besides, the porous two-dimensional layered structure of COF-Co with abundant defects can also promote the shortened diffusion distance of ion/electron with promoted K⁺ insertion/extraction ability. Enhanced cycling stability with large reversible capacity (371 mAh g^-1 after 400 cycles at 100 mA g^-1) and good rate properties (105 mAh g^-1 at 2000 mA g^-1) have been achieved for the COF-Co electrode.

Zhou, Bei;He, Yu-Juan;Tao, Yun-Feng;Liu, Lan-Xiang;Hu, Min;Chang, Zu-Hui;Lei, Hong;Lin, Jun;Lin, Tong;Du, Guan-Ben research published 《 Electrocatalytic synthesis of α,α-gem-dihalide ketones from α-mono-halide ketones and unexpected dimer condensation》, the research content is summarized as follows. A novel, environmentally friendly electrocatalytic process was developed to prepare α,α-gem-dihalide (F, Cl, and Br) ketones from α-mono-halide ketones in an aqueous solution containing alkali halide salts. The gem-dihalides had the same or different halogens on the same carbon, depending on the reactant and inorganic halide salt used. An electron-withdrawing group, such as carbonyl, located at the α-site of mono-halogenated carbon, was essential to the reaction. The electrosyntheses were performed under ambient conditions without inert gas protection and displayed yields of about 80%. This method avoided the classical haloform elimination reaction. However, when the aqueous solution contained NaOH, two α-mono-halide ketone mols. had a special dimer condensation. The reaction mechanisms were explored by conducting GC-MS, EPR, and CV with DFT calculations These revealed that in situ generation of a halogen radical initiated electrocatalytic halogenation, while the dimer condensation involved a hydroxyl radical-mediated C1 fragment elimination.
