use | methyl o-bromobenzoate is a colorless or yellowish transparent liquid and can be used as an intermediate in organic synthesis. |
preparation | preparation of methyl o-bromobenzoate: in a 250ml three-mouth bottle, adding 0.04mol of raw material methyl benzoate and 100ml of acetic acid, stirring and dissolving, and then cooling to 0 ℃ in an ice salt bath; Dissolve 0.05mol Br2 in 50ml acetic acid, slowly drop bromine acetic acid solution into the above reaction system, after dropping, control the temperature to 20-25 ℃, stir the reaction for 12 hours, and the sampling point plate shows that there is no raw material I1-3 remaining; after the reaction is over, the NaOH aqueous solution is added dropwise to neutralize the reaction liquid, dichloromethane is added for extraction, stratified, and the organic phase is filtered, and the filtrate is distilled under reduced pressure To no fraction, pass through a neutral silica gel column to obtain the intermediate methyl o-bromobenzoate. |
