Process for preparing substituted phenylacetic acid derivatives and novel intermediates

Description here is a novel process for preparing phenyl acetic acid derivatives of the formula (I) in which Ar and R1 are as defined in the description by reaction of sulfonyloxy-activated hydroxyacetic acid derivatives of the formula (II) in which R3 is as defined in the description. with aromatics of the formula (III) has been found. The intermediates of the formula (II), some of which are novel, are obtained from hydroxyacetic acid derivatives by reaction with sulfonyl halides or sulfonic anhydrides. The phenylacetic acid derivatives are important starting materials for preparing pesticides.
