Abstract

During the reaction of the amides of benzo- and dibenzocrown thiocarboxylic acids with methyl iodide in the presence of potassium hydroxide they exhibit anomalous behavior leading to the nitriles of benzo- and dibenzocrown carboxylic acids. The nitriles of benzo-15-crown-5-, benzo-12-crown-4-, and dibenzo-18-crown-6-4′-carboxylic acids  and the dinitriles of dibenzo-18-crown-6- and dibenzo-24-8-4′,4″(5″)-dicarboxylic acids were obtained.
