Preparation and Reactions of CF3-Containing Phthalides was written by Mitobe, Kana;Terashima, Kyu;Kawasaki-Takasuka, Tomoko;Agou, Tomohiro;Kubota, Toshio;Yamazaki, Takashi. And the article was included in European Journal of Organic Chemistry in 2018.Formula: C10H8Br2O4 This article mentions the following:
We have demonstrated that reactions of aromatic 1,2-diesters and the Ruppert-Prakash reagent (TMSCF3) afforded hitherto unknown phthalides with both trifluoromethyl (CF3) and alkoxy groups at the 3 position. Their unique transformation was also investigated in detail to attain construction of a variety of very rare types of compounds, such as 1,3-dihydroisobenzofurans as well as indanones with a CF3 moiety, whose behavior was completely different from the structurally similar hydroxy compound In the experiment, the researchers used many compounds, for example, Dimethyl 4,5-dibromophthalate (cas: 859299-66-4Formula: C10H8Br2O4).
Dimethyl 4,5-dibromophthalate (cas: 859299-66-4) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Formula: C10H8Br2O4
