《Ligand-Free Iron-Catalyzed Homo-Coupling of Aryllithium Reagents》 was published in Asian Journal of Organic Chemistry in 2020. These research results belong to Wang, Zhi-Yong; Peng, Xiao-Shui; Wong, Henry N. C.. Safety of 1-Bromo-3,4,5-trimethoxybenzene The article mentions the following:
The synthesis of sym. biaryls via the iron-catalyzed homo-coupling of aryllithium reagents was developed under a mild condition, in the absence of ligand, with wide range of scope, and in good yields. Investigation on reaction concentration and practical utility of this environmentally friendly procedure also indicates a promising application outlook. The experimental process involved the reaction of 1-Bromo-3,4,5-trimethoxybenzene(cas: 2675-79-8Safety of 1-Bromo-3,4,5-trimethoxybenzene)
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.Safety of 1-Bromo-3,4,5-trimethoxybenzene1-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.
