- Method for preparing iodo-benzoic acid (ester) by improving moral Michael reaction
-
The invention discloses a method for preparing iodo-benzoic acid (ester) by improving a moral reaction, and belongs to the technical field of organic synthesis. The method comprises the following steps: preparing and separating the diazonium tetrafluoroborate through diazotization of aminobenzoic acid (ester) and then performing iodination reaction with the iodinated reagent in an organic medium to obtain the corresponding iodo carboxylic acid (ester). The iodo-benzoic acid (ester) prepared by the method has high purity. The method has the advantages of good quality and simple post-treatment, and the product yield reaches 70 - 90%.
