《Stepwise Mechanism for the Bromination of Arenes by a Hypervalent Iodine Reagent》 was published in Journal of Organic Chemistry in 2020. These research results belong to Granados, Albert; Shafir, Alexandr; Arrieta, Ana; Cossio, Fernando P.; Vallribera, Adelina. Product Details of 523-27-3 The article mentions the following:
A mild, metal-free bromination method of arenes has been developed using the combination of bis(trifluoroacetoxy)iodobencene and trimethylsilyl bromide. In situ-formed dibromo(phenyl)-λ3-iodane (PhIBr2) is proposed as the reactive intermediate. This methodol. using PIFA/TMSBr has been applied with success to a great number of substrates (25 examples). The treatment of mono-substituted activated arenes led to para-brominated products (2u-z) in excellent 83-96% yields. D. functional theory calculations indicate a stepwise mechanism involving a double bromine addition followed by a type II dyotropic reaction with concomitant re-aromatization of the six-membered ring. The results came from multiple reactions, including the reaction of 9,10-Dibromoanthracene(cas: 523-27-3Product Details of 523-27-3)
9,10-Dibromoanthracene(cas: 523-27-3) can be sublimated and oxidized to generate anthraquinone. Soluble in hot benzene and hot toluene, slightly soluble in alcohol, ether and cold benzene, insoluble in water.Product Details of 523-27-3
