Potassium benzofuran-2-yltrifluoroborate (cas: 929626-27-7) belongs to benzofurans derivatives. Benzofuran is the “”parent”” of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants. In nature, benzofurans have occupied an important role among the plant phenols & several pharmacologically active compounds.Application of 929626-27-7

Halodeboronation of organotrifluoroborates using tetrabutylammonium tribromide or cesium triiodide was written by Yao, Min-Liang;Kabalka, George W.;Blevins, David W.;Reddy, Marepally Srinivasa;Yong, Li. And the article was included in Tetrahedron in 2012.Application of 929626-27-7 This article mentions the following:

Halodeboronation of organotrifluoroborates using com. available tetrabutylammonium tribromide (TBATB) or cesium triiodide in aqueous medium is reported. The mild, transition metal-free method has proven to be tolerant of a wide range of functional groups. High regio- and chemoselectivity are observed Two synthetic routes to (Z)-dibromoalkenes from alkynes, through stereodefined (Z)-2-bromoalkenyltrifluoroborates and (Z)-1,2-bis(boryl)alkenyltrifluoroborates, have been developed using the TBATB mediated bromodeboronation as the key step. In the experiment, the researchers used many compounds, for example, Potassium benzofuran-2-yltrifluoroborate (cas: 929626-27-7Application of 929626-27-7).
