This invention relates to a process for preparing an alpha-arylalkanoic acid or salt thereof which comprises the rearrangement of an alpha-halo-alkylarylketal in neutral or slightly alkaline conditions, in the presence of a dipolar aprotic diluent and of a protic substance having a high dielectric constant, and the subsequent hydrolysis of the thus obtained ester.
本发明涉及一种制备α-芳基烷酸或其盐的工艺,该工艺包括在中性或微碱性条件下,在双极性烷基稀释剂和具有高介电常数的原生质存在下,对α-卤代芳基酮进行重排,然后对由此得到的酯进行水解。
