Reaction with hydrazonoyl halides 64: Synthesis of some new triazolino[4,3-a]pyrimidines, 1,3,4-thiadiazoles, and 5-arylazothiazoles was written by Abdelhamid, Abdou O.;Fahmi, Abdelgawad A.;Baaui, Basma S.. And the article was included in Journal of Heterocyclic Chemistry in 2012.Formula: C10H7BrO2 This article mentions the following:
2,3-Dihydro-1,3,4-thiadiazoles, 2,3-dihydro-1,3,4-selenadiazoles, and triazolino[4,3-a]pyrimidines containing a benzofuran moiety were prepared from the reaction of 2-(2-phenylhydrazono)-1-(5-bromobenzofuran-2-yl)-2-chloroethanone with KSCN, KSeCN, alkyl carbodithioates, and pyrimidine-2-thiones, resp. In the experiment, the researchers used many compounds, for example, 1-(5-Bromobenzofuran-2-yl)ethanone (cas: 38220-75-6Formula: C10H7BrO2).
1-(5-Bromobenzofuran-2-yl)ethanone (cas: 38220-75-6) 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. Substituted benzofurans find applications such as fluorescent sensors, oxidants, in drug discovery, and in another field of chemistry and agriculture.Formula: C10H7BrO2
