Preparation method for o-tolylacetic acid aryl formic acid derivative

The invention discloses a preparation method for an o-tolylacetic acid aryl formic acid derivative. According to the method, new C-C bonds can be formed, the organic o-tolylacetic acid aryl formic acid derivative is obtained, the good functional group tolerance is achieved, and the o-tolylacetic acid aryl formic acid derivative which cannot be easily obtained by adopting other methods can be synthesized; according to the method, adopted raw materials are easy to obtain, the yield is high, the reaction conditions are mild, the substrate range is wide, and after-treatment is simple and green.

Process for preparing 4, 5-dichloro-2-methylbenzoic acid

The present invention relates to a process for preparing 4,5-dichloro-2-methylbenzoic acid and also its salts in high yields and in high purities by reacting 3,4-dichlorotoluene with acetyl chloride or chloroacetyl chloride in the presence of a Friedel-Crafts catalyst and subsequently oxidizing the acetylated intermediate to give the carboxylic acid.
