Reaction Conditions:

with dihydrogen peroxide;acetic acid;potassium bromide at 20; for 10 h;Temperature;

Steps:

1
4 mmol2-naphthoic acid and4 mmol potassium bromide was placed in a round bottom flask,5 ml of acetic acid was added,Stirring dropwise 4mmolHydrogen peroxide (30%), 20 ° C under stirring reaction 10h,After being cooled for 12h at 0 ° C, the product was filtered to obtain pale yellow needle-like crystals. After drying, the products were analyzed by IR and 1H-NMR.The yield was calculated by weighing, under the above conditionsThe yield of 1-bromo-2-naphthol was 82%.
