In 2011,Tetrahedron included an article by Bolla, Krishnavenu; Kim, Taejung; Song, Jung Ho; Lee, Seokjoon; Ham, Jungyeob. Reference of potassium (3-bromophenyl)trifluoroborate. The article was titled 《Efficient and rapid synthesis of regioselective functionalized potassium 1,2,3-triazoletrifluoroborates via 1,3-dipolar cycloaddition》. The information in the text is summarized as follows:
In this study, we present a previously unreported method of preparing regiospecific organo-[1,2,3]-triazol-1-aryl-trifluoroborates from haloaryltrifluoroborates via a one-pot 1,3-dipolar cycloaddition reaction. We found that the use of either electron-rich or electron-deficient haloaryltrifluoroborates led to the desired cycloaddition products with good to excellent yields. Furthermore, we successfully carried out the cross-coupling reactions of the obtained triazoles with various aryl halides by means of the Suzuki-Miyaura reaction in the presence of 3 mol % of Pd(PPh3)4 catalyst in a 20% aqueous 1,4-dioxane solution at 100 °C; all these reactions yielded complete conversion to the corresponding products. Besides providing a high level of personnel safety, our highly versatile approach allows the preparation of functionalized organotrifluoborates containing 1,2,3-triazoles with retained functionality.potassium (3-bromophenyl)trifluoroborate(cas: 374564-34-8Reference of potassium (3-bromophenyl)trifluoroborate) was used in this study.
potassium (3-bromophenyl)trifluoroborate(cas: 374564-34-8) belongs to organobromine compounds.Depending on the type of carbon to which the bromine is bonded, organic bromide could be alkyl, alkenyl, alkynyl, or aryl. Due to the reactivity of bromide, they are used as potential precursors or important intermediates in organic synthesis. Reference of potassium (3-bromophenyl)trifluoroborate
