Organic bromides such as alkyl bromides are used as fumigants in agriculture to control insects. 1575-37-7, formula is C6H7BrN2, Name is 4-Bromobenzene-1,2-diamine. Ethylene bromide is one of the commercially important organic bromides which are the component of leaded gasoline. Synthetic Route of 1575-37-7.
Zheng, Leizhi;Yang, Guoqiang;Liu, Jia;Jiang, Bowen;Yu, Ting;Hu, Xingbang;Zhang, Zhibing research published 《 Efficient chemical fixation of CO2 to form switchable ionic liquid to synthesize benzimidazolones under mild conditions》, the research content is summarized as follows. In this work, a novel pathway to synthesize benzimidazolone derivatives I [R = 5-Me, 5-MeO, 5,6-di-Me] via the carbonylation of o-phenylenediamines with carbon dioxide under mild conditions (e.g., 50°C, 0.5 MPa) in the presence of 1,5-diazabicyclo[4.3.0]non-5-ene (DBN) was reported. In this progress, the DBN, acting as superbase, could form strong intermol. hydrogen bonds with o-phenylenediamines. The carbon dioxide was chem. fixed to form switchable ionic liquids (SILs). Then, CH2Br2 as a dehydrant easily involved parallel attack carbamates salts to form leaving group. To the best of our knowledge, this protocol provided a sustainable technique for the production of benzimidazolones under mild conditions.
1575-37-7, 4-Bromo-1,2-diaminobenzene can be obtained from 1,2-diaminobenzene via acetylation followed by bromination and alkaline hydrolysis.
4-Bromobenzene-1,2-diamine, also known as 4-Bromobenzene-1,2-diamine, is a useful research compound. Its molecular formula is C6H7BrN2 and its molecular weight is 187.04 g/mol. The purity is usually 95%.
4-Bromo-1,2-diaminobenzene is a dye that is used in diagnostic
procedures to detect the presence of amide groups. 4-Bromo-1,2-diaminobenzene can be used as an inhibitor for cationic polymerization reactions. It also has tuberculostatic activity and inhibits the growth of Mycobacterium tuberculosis. This compound reacts with aniline to form a benzimidazole derivative that contains a reactive amine group. The reaction between this amine group and different electrophiles generates benzimidazole compounds with different properties that are useful in nucleophilic attack reactions. The reaction between 4-bromo-1,2-diaminobenzene and methyl ethyl sulfide produces a luminescent probe that can be used to detect hydrogen bonds., Synthetic Route of 1575-37-7
