Phase-transfer-catalytic Synthesis of 1-Naphthalene Acetic Acid by Octacarbonyl Dicobalt

1-Naphthalene acetic acid was synthesized from 1-chloromethyl naphthalene byoctacarbonyl dicobalt under phase transfer catalytic conditions. Conversion was 99% andyield 83%. The effects of reaction temperatures, ratios of reactants, solvents, contents ofcatalyst and concentration of alkali on conversion have been investigated. Among the phasetransfer catalysts tested, the most effective was hexadecyltrimethylammonium chloride.
