Intramolecular cyclization of the pyridoxal-histidine Schiff base controlled in reversed micelles

Exploitation of reversed micelles as a medium in analytical chemiluminescence measurements with application to the determination of hydrogen peroxide using luminol

“…The choice of the bulk nonpolar solvent mixture was dictated by solubility considerations. Namely, quaternary ammonium surfactants, as CTAC, are reportedly only very sparingly soluble in inert aliphatic hydrocarbons (41) but are soluble in aromatic or chlorinated aliphatic hydrocarbons, especially carbon tetrachloride and chloroform (41)(42)(43)(44). A brief survey of the literature revealed that 1:1 or 6:5 (v/v) mixtures of a chlorinated and aliphatic hydrocarbon were commonly employed as the bulk solvent for physicochemical studies involving CTAB or CTAC reversed micelles (25,(45)(46)(47)(48).…”
