Abstract
Disclosed herein is a method for preparing a 2-arylmalonic acid derivative. In this method, a cyclohexadiene compound is used as a raw material, and sequentially undergoes an isomerization reaction, a halogenation reaction in the presence of a halogenating agent and a dehydrohalogenation-aromatization reaction to obtain a 2-arylmalonic acid derivative (3). An intermediate for preparing the 2-arylmalonic acid derivative (3) and use of the intermediate are also disclosed.
