In 2019,Angewandte Chemie, International Edition included an article by Yang, Zhongming; Zhao, Weijia; Liu, Wei; Wei, Xing; Chen, Meng; Zhang, Xiao; Zhang, Xiaolei; Liang, Yong; Lu, Changsheng; Yan, Hong. Computed Properties of C7H9NO. The article was titled 《Metal-Free Oxidative B-N Coupling of nido-Carborane with N-Heterocycles》. The information in the text is summarized as follows:
A general method for the oxidative substitution of nido-carborane (7,8-C2B9H12-) with N-heterocycles has been developed by using 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) as an oxidant, producing 9-Het-7,8-R2-7,8-dicarbaundecaboranes(11) [Het = pyridine, (iso)quinoline, (benz)imidazole, (benzo)thiazole, oxazole, pyrazole, pyrimidine 6-azaindole; R = Ph, H, Me, tBu, RR = CH2CH:CHCH2]. This metal-free B-N coupling strategy, in both inter- and intramol. fashions, gave rise to a wide array of charge-compensated, boron-substituted nido-carboranes in high yields (up to 97%) with excellent functional-group tolerance under mild reaction conditions. The reaction mechanism was investigated by d.-functional theory (DFT) calculations A successive single-electron transfer (SET), B-H hydrogen-atom transfer (HAT), and nucleophilic attack pathway is proposed. This method provides a new approach to nitrogen-containing carboranes with potential applications in medicine and materials. In the part of experimental materials, we found many familiar compounds, such as 2-(2-Hydroxyethyl)pyridine(cas: 103-74-2Computed Properties of C7H9NO)
2-(2-Hydroxyethyl)pyridine(cas: 103-74-2) belongs to pyridine. Pyridines are often used as catalysts or reagents; particular notice has been paid recently to how pyridine coordinates to metal centers enabling a wide range of valuable reactions. Computed Properties of C7H9NO
