Abstract
A direct, essentially one-step method of preparing nuclearly chlorinated naphthalene esters which comprises forming a reaction mixture consisting essentially of a mono- or dicarboalkoxy substituted naphthalene, a chlorinated organic solvent having from 1 to 4 carbon atoms and a chlorination catalyst, heating the reaction mixture, and passing molecular chlorine into the mixture. The extent of the chlorination of the naphthalene mono- or diester can be controlled by varying the solvent employed, the amount of chlorine added and the reaction time. A number of unreported polychlorinated naphthalene esters and an acid chloride are obtained directly by the method. The esters can be used in the production of coloring materials, plastics and insecticides.
