Shen, Yuqing;Yuan, Chaoping;Zhu, Xianyi;Chen, Qin;Lu, Shenjun;Xie, Haibo research published 《 Engineering cellulose into water soluble poly(protic ionic liquid) electrolytes in the DBU/CO₂/DMSO solvent system as an organo catalyst for the Knoevenagel condensation reaction》, the research content is summarized as follows. Herein, linear water soluble cellulosic poly(protic ionic liquid) (CPIL) electrolytes were facilely and atom economically prepared after the dissolution of cellulose in the newly developed DBU/CO₂/DMSO solvent system, followed by the simple addition of succinic anhydride under mild conditions. The DBU not only participated in the dissolution of cellulose as a solvent component, but also acted as an organo catalyst for the acylation reaction of cellulose with succinic anhydride, as well as cation component in the targeted CPIL electrolytes. The reaction was optimized, and the effect of the reaction conditions on the chem. and phys. properties of the CPILs was investigated. The CPIL electrolyte aqueous solution was successfully used as the catalytic reaction media for the Knoevenagel condensation reaction. It was found that the reaction was homogeneous at the beginning, and the products could precipitate out from the media with the proceeding of the reaction, thus affording satisfactory filtration yields ranging from 56.7% to 93.8%. The solution properties of the CPIL aqueous solution were primarily investigated towards an in-depth understanding of the catalytic mechanism, by which a synergetic catalytic mechanism of the CPILs was proposed, and the reaction started with a nucleophilic addition reaction, and was then followed by a fast dehydration reaction. Finally, the direct reusability potential of the CPIL aqueous solution after the product filtration was also primarily investigated for the Knoevenagel condensation reaction.

Shang, Xiao;Liu, Xuan;Sun, Yujie research published 《 Flexible on-site halogenation paired with hydrogenation using halide electrolysis》, the research content is summarized as follows. Direct electrochem. halogenation has appeared as an appealing approach in synthesizing organic halides in which inexpensive inorganic halide sources are employed and elec. power is the sole driving force. However, the intrinsic characteristics of direct electrochem. halogenation limit its reaction scope. Herein, we report an on-site halogenation strategy utilizing halogen gas produced from halide electrolysis while the halogenation reaction takes place in a reactor spatially isolated from the electrochem. cell. Such a flexible approach is able to successfully halogenate substrates bearing oxidatively labile functionalities, which are challenging for direct electrochem. halogenation. In addition, low-polar organic solvents, redox-active metal catalysts, and variable temperature conditions, inconvenient for direct electrochem. reactions, could be readily employed for our on-site halogenation. Hence, a wide range of substrates including arenes, heteroarenes, alkenes, alkynes, and ketones all exhibit excellent halogenation yields. Moreover, the simultaneously generated H₂ at the cathode during halide electrolysis can also be utilized for on-site hydrogenation. Such a strategy of paired halogenation/hydrogenation maximizes the atom economy and energy efficiency of halide electrolysis. Taking advantage of the on-site production of halogen and H₂ gases using portable halide electrolysis but not being suffered from electrolyte separation and restricted reaction conditions, our approach of flexible halogenation coupled with hydrogenation enables green and scalable synthesis of organic halides and value-added products.
