1-(5-Bromobenzofuran-2-yl)ethanone (cas: 38220-75-6) belongs to benzofurans derivatives. Benzofuran is a core structural unit found in many naturally occurring compounds with multidirectional biological activities. Substituted benzofurans find applications such as fluorescent sensors, oxidants, in drug discovery, and in another field of chemistry and agriculture.COA of Formula: C10H7BrO2

Stereoretentive Pd-catalysed Stille cross-coupling reactions of secondary alkyl azastannatranes and aryl halides was written by Li, Ling;Wang, Chao-Yuan;Huang, Rongcai;Biscoe, Mark R.. And the article was included in Nature Chemistry in 2013.COA of Formula: C10H7BrO2 This article mentions the following:

Racemic and nonracemic secondary stannatranes I [R = EtCHMe, Me2CH, 4-tetrahydropyranyl, (EtO2CCH2)CHMe, 3-octyl, PhCHMe, 1-methyl-4-piperidinyl, PhCH2CH2CHMe, (S)-PhCH2CH2CHMe, (S)-1-Boc-2-pyrrolidinyl] were prepared; I underwent regioselective Stille coupling reactions with aryl halides and triflates in the presence of bis(dibenzylideneacetone)palladium, the JackiePhos ligand II [R1 = 3,5-(F3C)2C6H3], CuCl, and KF to yield secondary alkyl-substituted arenes such as Et 4-(2-butyl)benzoate in 26-94% yields (two of 23 reactions < 50% yield). Aryl halides and triflates with electron-donating and electron-withdrawing substituents were tolerated. Coupling of I [R = (S)-PhCH2CH2CHMe, 94% ee] with 2-bromopyridine or 2-bromo-6-methylquinoline yielded the coupling products with almost complete retention of stereochem. in 91-92% ee. The structure of a nonracemic (bromobenzoyl)pyrrolidinylbenzonitrile was determined by X-ray crystallog. In the experiment, the researchers used many compounds, for example, 1-(5-Bromobenzofuran-2-yl)ethanone (cas: 38220-75-6COA of Formula: C10H7BrO2).
