The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 1-(Bromomethyl)-4-ethylbenzene, is researched, Molecular C9H11Br, CAS is 57825-30-6, about Direct conversion of alkyl halides into benzimidazoles using pyridine-N-oxide and 1,2-diaminobenzenes, the main research direction is benzimidazole preparation; diaminobenzene aralkyl bromide pyridine oxide three component oxidation.Application of 57825-30-6.
Benzimidazole heterocycles I [R1 = C6H5, 4-CH3CH2C6H4, 4-FC6H4, 1H-pyrrol-2-yl, etc.; R2 = H, 5-OCH3, 5-CH3] were obtained from halogenated compounds R1CH2Br and aromatic 1,2-diamines such as o-phenylenediamine, 4-methyl-1,2-benzenediamine, 4-methoxy-1,2-benzenediamine. A mild oxidizing reagent such as pyridine N-oxide is required to produce the benzimidazole core I. The method is solvent-free and provides products without the need for chromatog. Good yields, moderate reaction temperature, and fast reaction rates are important advantages of this procedure.
