Literature References
Reacts with Na metal in 1,2-dimethoxyethane to give Na naphthalenide. This radical anion is a powerful-electron donor, e.g. in reductive dehalogenation of vic-dihalides: J. Chem. Soc., Chem. Commun., 78 (1969), and in reductive cleavage of tosylates to alcohols: J. Am. Chem. Soc., 88, 1581 (1966). Li naphthalenide is a useful, non-nucleophilic reagent for the conversion of carboxylic acids to their dianions in cases where LDA could interfere: J. Org. Chem., 45, 1106 (1980). Similarly, has been found preferable to LDA in the lithiation of allylic nitriles: Synthesis, 358 (1981). Carboxylic acids react with alkyl, alkenyl or aryl chlorides in the presence of Li metal and a catalytic amount of naphthalene in THF to give ketones in fair to good yields: J. Org. Chem., 61, 6058 (1996).
Applications
Naphthalene is formerly important in dyestuff manufacture. It acts as a precursor to phthalic anhydride. Naphthalene is used in the manufacturing of phthalic anhydride, naphthalene sulfonic acids and hydrogenated naphthalenes such as 1,2,3,4-tetrahydronaphthalene, which is used as a precursor for various dyestuffs, pigments, rubber processing chemicals and in pharmaceuticals. Its molten form is used as solvent replacing the high- boiling solvents like dichlorobenzene, nitrobenzene and durene. It is involved as reaction medium for in the Diels-Alder reaction between C60 with anthracene.
