In 2019,ACS Catalysis included an article by Zhao, Qun; Zhang, Jin; Szostak, Michal. Application In Synthesis of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane. The article was titled 《Ruthenium(0)-Catalyzed Cross-Coupling of Anilines with Organoboranes by Selective Carbon-Nitrogen Cleavage》. The information in the text is summarized as follows:

Selective activation of neutral carbon-nitrogen bonds is of great synthetic importance, because amines are among the most prevalent motifs across organic and bioactive mols. Herein, we report the Ru(0)-catalyzed selective cleavage of neutral C(aryl)-N bonds in generic aniline derivatives enabled by a combination of Ru3(CO)12 and an imino auxiliary. These mild conditions provide a direct route to high-value biaryl ketones and biaryl aldehydes after facile in situ hydrolysis. A broad range of organoboranes and anilines can be coupled with high C-N cleavage selectivity. Most crucially, the reaction achieves exquisite selectivity for activation of C(aryl)-N bonds in the presence of typically more kinetically favorable C(aryl)-H bonds. The method provides a strategy for the construction of functionalized terphenyls by exploiting orthogonal properties of the Ru(0) catalyst system and traceless nucleophilic properties of anilines. In the experiment, the researchers used many compounds, for example, 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Application In Synthesis of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane)

《Two novel MOFs@COFs hybrid-based photocatalytic platforms coupling with sulfate radical-involved advanced oxidation processes for enhanced degradation of bisphenol A》 was written by Lv, Shi-Wen; Liu, Jing-Min; Li, Chun-Yang; Zhao, Ning; Wang, Zhi-Hao; Wang, Shuo. Quality Control of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde And the article was included in Chemosphere in 2020. The article conveys some information:

Herein, for the first time, two novel MOFs@COFs hybrid materials (denoted as MIL-101-NH2@TpMA and UiO-66-NH2@TpMA) with nitrogen-rich building blocks were fabricated via a feasible step-by-step assembly method, and then employed as efficient photocatalytic platform coupling with sulfate radical-based advanced oxidation processes for the degradation of BPA under visible light irradiation Detailed analyses revealed that the hybridization of MOFs and COFs could greatly boost visible light absorption, while the heterojunction formed at the interface could effectively facilitate the separation and transfer of photogenerated electron-hole pairs. More importantly, the developed solar/MOFs@COFs/PS system exhibited the excellent degradation ability toward BPA, and an incredible degradation efficiency of 99% was eventually achieved. Possible mechanism for photocatalytic degradation of BPA was also proposed. Furthermore, the prepared composites with great reusability and stability possessed a broad potential for highly effective degradation of various organic contaminants. In short, this work not only demonstrated the combination of MOFs and COFs with C3N4 active unit was a feasible strategy for improving photocatalytic activities in the degradation of organic contaminants, but also provided some novel inspirations for constructing high-efficient photocatalysts with heterostructure.

《Anti-recurrence/metastasis and chemosensitization therapy with thioredoxin reductase-interfering drug delivery system》 was written by Yang, Jichun; Pan, Shuojiong; Gao, Shiqian; Dai, Yiheng; Xu, Huaping. Electric Literature of C3H7BrO And the article was included in Biomaterials in 2020. The article conveys some information:

Thioredoxin reductase (TrxR) is an essential mammalian enzyme that possesses a selenocysteine active site. TrxR is overexpressed in many malignant tumors and has a close relationship with apoptosis, drug resistance, recurrence and metastasis of tumors. Recently, TrxR has emerged as a promising target for anticancer therapy. Herein, we developed a TrxR-interfering drug delivery system (DDS) based on RGD-PEG-PUSeSe-PEG-RGD self-assembling micelles for imaging-guided gemcitabine (GEM) chemosensitization and anti-recurrence/metastasis therapy. The diselenide-containing micelles were degraded in response to TrxR stimuli for GEM releasing. In the meantime, the dissociated polymers′ chain segments targeted the active site of TrxR via Se-Se/Se-S dynamic reactions for activity inhibition. This inhibition by the micelles not only provided chemosensitization, but reduced tumor recurrence/metastasis risk via the induction of residual tumor cell apoptosis by triggering ROS production post-chemotherapy. In this work, we took the transformation between Se-containing dynamic covalent bonds developed by our group from in vitro to in vivo, which furthered the knowledge on the biochem. of selenium and provided aspects to develop new TrxR inhibitors. Overall, the TrxR-interfering DDS combined excellent antitumor effects for primary solid tumors with the inhibition of tumor recurrence/metastasis during post-treatment care, providing new perspectives for efficient cancer therapy. After reading the article, we found that the author used 3-Bromopropan-1-ol(cas: 627-18-9Electric Literature of C3H7BrO)
