Tashiro, Masashi; Nakayama, Kouji published the artcile< Preparation of bromobenzoic acids from the corresponding bromotoluenes via the Krohnke method>, Recommanded Product: 2,3-Dibromobenzoic acid, the main research area is benzoic acid dibromo; bromobenzoic acid; bromotoluene conversion bromobenzoic acid.
Bromotoluenes were converted to acids I (n = 2, 3) via N-benzylpyridinium salts II. Thus, 2,3-Br2C6H3Me was brominated to 2,3-Br2C6H3CH2Br, the latter and pyridine gave II (Brn = 2,3-Br2), the product was treated with 4-Me2NC6H4NO and then with HCl to yield 2,3-Br2C6H3CHO, and the aldehyde was oxidized by KMnO4 to give 2,3-Br2C6H3CO2H.
Organic Preparations and Procedures International published new progress about 603-78-1. 603-78-1 belongs to class bromides-buliding-blocks, and the molecular formula is C7H4Br2O2, Recommanded Product: 2,3-Dibromobenzoic acid.
