Ushijima, Sousuke published the artcileOne-pot conversion of aromatic bromides and aromatics into aromatic nitriles, Synthetic Route of 5653-62-3, the main research area is aryl bromide cyanation sequential lithiation DMF addition; arene cyanation sequential lithiation DMF addition; aromatic nitrile green preparation.

Various aromatic bromides and iodides were smoothly converted into the corresponding aromatic nitriles in good to moderate yields by sequential treatment with BuLi and DMF, followed by treatment with I2 in aqueous NH3. The same treatment of typical aromatics and heteroaromatics also provided the corresponding aromatic nitriles in good yields. The present reactions are novel 1-pot methods for the preparation of aromatic nitriles from aromatic bromides and aromatics, resp., through the formation of aryllithiums and their DMF adducts.

Hendrick, Charles E. published the artcileInsertion of Arynes into N-Halo Bonds: A Direct Approach to o-Haloaminoarenes, Quality Control of 204078-32-0, the main research area is haloaminoarene regioselective preparation; insertion aryne nitrogen halo bond.

A new approach to access o-haloaminoarenes has been achieved by insertion of arynes into a nitrogen-halide bond (N-X). This transition-metal-free transformation displays a broad substrate scope of arynes, good compatibility with functional groups, and high regioselectivity. Representative transformations of the o-haloaminoarenes are described to highlight their utility for rapid access to diversely functionalized aminoarene derivatives E.g., treating morpholine with NCS, followed by addition of 2-(trimethylsilyl)phenyl triflate and CsF, gave 67% o-haloaminoarene derivative (I).

Synthesis and biol. evaluation of a novel class of substituted N-benzyl-1-(2,3-dichlorophenyl)-1H-tetrazol-5-amine derivatives resulted in the identification of potent P2X7 antagonists. These compounds were assayed for activity at both the human and rat P2X7 receptors. On the benzyl moiety, a variety of functional groups were tolerated, including both electron-withdrawing and electron-donating substituents. Ortho-substitution on the benzyl group provided the greatest potency. The ortho-substituted analogs showed approx. 2.5-fold greater potency at human compared to rat P2X7 receptors.

Zhao, Dongmu;Ouyang, Ancheng;Wang, Xianglei;Zhang, Wei;Cheng, Guanghui;Lv, Bin;Liu, Wei research published 《 Synthesis, crystal structure and biological evaluation of thyroid cancer targeting photosensitizer for photodynamic therapy》, the research content is summarized as follows. With the increasing of thyroid cancer worldwide, there urgently demands new mild theranostic strategies for treatment of recurrence of thyroid cancer to overcome the side-effects of the clin. practices (¹³¹I). In this work, photodynamic therapy (PDT) was first explored for treatment of thyroid cancer by incorporating iodomethane choline onto the phthalocyanine through either axial or peripheral substitution. Due to the extraordinary nonaggregation properties in aqueous solution, the axial choline substituted SiPc 1 shows much higher singlet oxygen generation and fluorescence emission than ZnPc 2 and 3 with peripheral substituted cholines. Their photodynamic activities in different type of thyroid cancer cells were clearly compared, disclosing that SiPc 1 is the most promising candidate for PDT of thyroid cancer.

Zhi, Qianjun;Jiang, Rong;Liu, Wenping;Sun, Tingting;Wang, Kang;Jiang, Jianzhuang research published 《 Atomic CoN₃S₁ sites for boosting oxygen reduction reaction via an atomic exchange strategy》, the research content is summarized as follows. It is vitally important to develop high-efficiency low-cost catalysts to boost oxygen reduction reaction (ORR) for renewable energy conversion. Herein, an A-CoN₃S₁@C electrocatalyst with at. CoN₃S₁ active sites loaded on N, S-codoped porous carbon was produced by an at. exchange strategy. The constructed A-CoN₃S₁@C electrocatalyst exhibits an unexpected half-wave potential (0.901 V vs. reversible hydrogen electrode) with excellent durability for ORR under alk. conditions (0.1 M KOH), superior to the com. platinum carbon (20 weight% Pt/C). The outstanding performance of A-CoN₃S₁@C in ORR is due to the pos. effect of S atoms doping on optimizing the electron structure of the at. CoN₃S₁ active sites. Moreover, the rechargeable zinc-air battery in which both A-CoN₃S₁@C and IrO₂ were simultaneously served as cathode catalysts (A-CoN₃S₁@C &IrO₂) exhibits higher energy efficiency, larger power d., as well as better stability, compared to the compound Pt/C&IrO₂-based zinc-air battery. The present result should be helpful for developing lower cost and higher performance ORR catalysts which is expected to be used in practical applications in energy devices.

Zhu, Lei;Liang, Gaolei;Guo, Chuanpan;Xu, Miaoran;Wang, Minghua;Wang, Changbao;Zhang, Zhihong;Du, Miao research published 《 A new strategy for the development of efficient impedimetric tobramycin aptasensors with metallo-covalent organic frameworks (MCOFs)》, the research content is summarized as follows. Two bimetallic CoNi-based metallo-covalent organic frameworks (MCOFs) were prepared and explored as the sensitive platforms of impedimetric aptasensors for efficient detection of tobramycin (TOB). The two CoNi-MCOFs were constructed using metallophthalocyanine tetra-amine (MPc-TA, M = Co²⁺ or Ni²⁺) and 4,4′-(1,10-phen-anthroline-2,9-diyl) dibenzaldehyde (PTD) as building units and further coordinating to the secondary metal ions (Ni²⁺ or Co²⁺) by phenanthroline. Interestingly, the immobilization ability of CoPc-TA-PTD(Ni) to TOB-targeted aptamer is higher than that of NiPc-TA-PTD(Co) due to its stronger binding interactions to aptamer. As a result, the CoPc-TA-PTD(Ni)-based aptasensor shows the superior TOB detection ability, giving a low detection limit of 0.07 fg mL^-1 and satisfied sensing performances, such as high selectivity, good reproducibility, and excellent stability. Also, the aptasensor shows the acceptable applicability for detecting TOB in milk or chicken egg. This MCOFs-based sensing strategy could be extensively applied to detect other analytes by anchoring the corresponding probes.

Zuo, Linsen;Wu, Chenjiang;Tong, Lifen;Liu, Xiaobo research published 《 Improving interfacial properties of polyarylene ether nitrile/aramid fiber composite through hydrogen bonding interaction combined with molecular weight adjustment》, the research content is summarized as follows. Aramid fiber (AF)-reinforced composite is a material with high performance and great potential. In this work, polyarylene ether nitrile terminated with phthalonitrile (PEN-t-Ph) is used to modify the AF surface, and hydrogen bonds are formed between the AF and PEN-t-Ph resin, as shown by Fourier IR anal. Then modified AF (m-AF)/PEN-t-Ph composite laminate is prepared by hot-pressing, and the influence of mol. weight of PEN-t-Ph on performance of the m-AF/PEN-t-Ph composite laminate is studied. The PEN-t-Ph were named PEN-1, PEN-2, PEN-3 and PEN-4 according to mol. weight from large to small. And the mech. properties and interface compatibility of m-AF/PEN-n composite laminates initially increase and then decrease as the mol. weight of the PEN-t-Ph resin decreases. The m-AF/PEN-3 composite laminate has the best mech. performance with an interlaminar shear strength of 94 MPa that is 95% higher than the lowest values among the four samples. In addition, m-AF/PEN-3 has the best impact strength of 133.70 kJ/m², and in the dynamic mech. anal. test, m-AF/PEN-3 has a leading storage modulus with 62 GPa at 120°C which is 50 GPa higher than for the lowest sample. In general, the mol. weight of the PEN-t-Ph resin has a greater impact on performance of the m-AF/PEN-t-Ph composite laminates, and appropriate adjustment of mol. weight of the PEN-t-Ph resin will help improve the comprehensive performance of the m-AF/PEN-t-Ph composite laminate and provides a new way for preparing AF-reinforced materials.
