Abstract
It was established that the gegenion in long-chain quaternary α-methylpyridinium salts affects their recyclization to anilines under the influence of amine sulfites. The yields of the final N-alkylanilines increase markedly in series of salts that contain chloride, bromide, and iodide anions; this is associated with micelle formation in aqueous solutions of these salts and the concentration of the amine that is localized in the micelle.
