Abstract
The four compounds:2-Methylphenol,catechol,m-dihydrobenzene and resorcinol,were used as starting materials in this paper.Firstly,the protection of hydroxyl group in the four compounds were performed using methyl iodide and methoxyethyl chloride as reagents.Then,in the present of acetic acid and ammonium molybdate which was used as catalysis,the production compounds were reacted with potassium bromide and hydrogen peroxide to afford bromination products on benzene ring.In conclusion,the experimental method was easily performed,the reaction time was short and the products were gained in high yield.The bromination was controlled by the large molecular structure of ammonium methylbdate.IR and 1H NMR were used to character the structures of the target compounds.
