Several recent reports suggest that arylboronic esters can exhibit room temperature phosphorescence (RTP), an optical property that is desirable for applications in security printing, oxygen sensing, and bioimaging. These findings challenge...
New CDDO Arylboronate Ester Derivatives with High Selectivity and Low Toxicity [0.03%]
高选择性低毒性的新型CDDO芳基硼酸酯衍生物

Na Li et al.
As an oleanolic acid derivative, CDDO-Me lacks selectivity for tumors. Based on the high reactive oxygen species (ROS) level in cancer cells, compound 4 was selected from 17 new CDDO arylboronate ester derivatives. A preliminary study revea...
Automation of Copper-Mediated 18F-Fluorination of Aryl Pinacol Boronates Using 4-Dimethylaminopyridinium Triflate [0.03%]

We report a novel and environmentally friendly method for the ipso-bromination of arylboronic acids by exploiting the oxone/KBr system. We discovered that CuBr can catalyze the reaction and increase the yield from 63 to 97%. We believe that...
RhIII-Catalyzed Direct Heteroarylation of Unactivated C(sp3)-H with N-Heteroaryl Boronates [0.03%]
RhIII催化未活化C(sp³)-H与N-杂芳基硼酸直接偶联反应
Rong Chi,Guang-Yu Xu,Zhen-Ang Liu et al.
Rong Chi et al.
Disclosed herein is a rhodium(III)-catalyzed direct heteroarylation reaction between unactivated aliphatic C(sp3)-H bonds in 2-alkylpyridines and heteroaryl organoboron reagents. This catalytic protocol is compatible with various heterocycl...
A Co(III)-peroxo-arylboronate complex formed by nucleophilic reaction of a Co(III)-peroxo species [0.03%]
由Co(III)-过氧化物阴离子物种亲核反应生成的Co(III)-过氧杂-aryl硼酸酯配合物
Yan Li,Suhashini Handunneththige,Wenting He et al.
Yan Li et al.
In this work, we report the generation and characterization of two new Co(III)-peroxo complexes 2 and 3. 2 is best described as a mononuclear CoIII-(O2) complex that exhibits an 18O-isotope sensitive OO bond stretching vibration at 845(-49)...
Recent investigations into deborylative (thio-/seleno-) cyanation of aryl boronic acids [0.03%]
近年关于芳基硼酸的脱氧氰化反应研究（含硫/硒）

Farnaz Behmagham et al.
In this review, we intend to summarize the most important discoveries in the deborylative (thio-/seleno-) cyanation of aryl boronic acids from 2006 to the end of 2023. Thus, the review is divided into three parts. The first section focuses ...
Effects of Ring Size and Steric Encumbrance on Boron-to-Palladium Transmetalation from Arylboronic Esters [0.03%]
芳基硼酸酯中环的大小和位阻对硼到钯转移金属化的影响
Connor P Delaney,Andrew F Zahrt,Vincent M Kassel et al.
Connor P Delaney et al.
The structure of the diol from which an arylboronic ester is derived dramatically influences the rate of transmetalation in the Suzuki-Miyaura cross-coupling reaction. Some esters undergo transmetalation more than 20 times faster than the p...
