Synthesis of substituted 4-aryloxypthalic acids based on 4-nitro-N-methylphthalimide

Abstract

Based on an activated aromatic nucleophilic substitution reaction between 4-nitro-N-methylphthalimide and phenols containing different substituents we obtained both identified and unidentified 4-aryloxy-N-methylphthalimides. Their alkaline hydrolysis gave 4-aryloxyphthalic acids.
