Recently I am researching about CARBON-HETEROATOM BONDS; GRIGNARD-REAGENTS; AROMATIC KETONES; ARYL HALIDES; NI; ETHERS; ACTIVATION; CLEAVAGE; EXPLORATION; ANISOLES, Saw an article supported by the National Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [21572175, 21702028, 21871186, 21971168]; Department of Science and Technology of Jilin Province [20180520206JH]. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Tang, JH; Liu, LL; Yang, SR; Cong, XF; Luo, MM; Zeng, XM. The CAS is 93-02-7. Through research, I have a further understanding and discovery of 2,5-Dimethoxybenzaldehyde. Recommanded Product: 2,5-Dimethoxybenzaldehyde
We report here the first example of cross-coupling between two different and unactivated C(aryl)-O bonds with chromium catalysis. The combination of a low-cost Cr(II) salt, 4,4′-di-tart-butyl-2,2′-dipyridyl (dtbpy) as the ligand, and magnesium as the reductant shows high reactivity in promoting the reductive cross-coupling of aryl methyl ether derivatives with aryl esters by cleavage and coupling of two different C(aryl)-O bonds under mild conditions. The formation of active low-valent Cr species by reduction of CrCl2 with Mg can be considered, which prefers to initially activate the C(aryl)-O bond of phenyl methyl ether with the chelation help of dtbpy and an o-imine auxiliary. The subsequent consecutive reduction, second C(aryl)-O activation, and reductive elimination allow for the achievement of selective cross-coupling of C(aryl)-O/C(aryl)-O bonds.
Recommanded Product: 2,5-Dimethoxybenzaldehyde. Bye, fridends, I hope you can learn more about C9H10O3, If you have any questions, you can browse other blog as well. See you lster.
