In 2022,Liu, Xinyu; Wang, Zhifan; Wang, Qiwei; Wang, Yuanhua published an article in Angewandte Chemie, International Edition. The title of the article was 《Rhodium(II)-Catalyzed C(sp3)-H Diamination of Arylcyclobutanes》.COA of Formula: C9H11BrO3 The author mentioned the following in the article:
Activated by multiple consecutive oxidative radical-polar crossover and desaturation processes, the selective diamination of arylcyclobutanes, which is difficult to perform by classical metallonitrene C-H insertion, was achieved in a short time by rhodium(II) catalysis using N-fluorobenzenesulfonimide (NFSI) as the oxidant and nitrogen source.1-Bromo-3,4,5-trimethoxybenzene(cas: 2675-79-8COA of Formula: C9H11BrO3) was used in this study.
1-Bromo-3,4,5-trimethoxybenzene(cas: 2675-79-8) is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff.COA of Formula: C9H11BrO31-Bromo-3,4,5-trimethoxybenzene can be used to synthesize symmetric 3,3′,4,4′,5,5′-hexamethoxydiphenylacetylene via Stille-type coupling with bis-(tributylstannyl)acetylene.
