And the article was published in Organic & Biomolecular Chemistry in 2018. Quality Control of potassium (3-bromophenyl)trifluoroborate The author mentioned the following in the article:
A one-pot protocol of double Suzuki-Miyaura reactions was developed for the synthesis of unsym. teraryls. In the absence of a ligand, potassium bromophenyltrifluoroborate reacted with arylboronic acid and then sequentially with a hetero/aryl bromide by controlling the reaction temperature, providing unsym. p- and m-teraryl compounds in moderate to good overall yields. This protocol provided a convenient and practically approached to unsym. terphenyls under ligand-free and aerobic conditions.potassium (3-bromophenyl)trifluoroborate(cas: 374564-34-8Quality Control 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. Quality Control of potassium (3-bromophenyl)trifluoroborate
