摘要: The acylation of a naphthalene compound, substituted in the 2-position with an electron-donating group, with a reactive derivative of a lower aliphatic acid, in an aprotic organic diluent and in the presence of a Friedel Crafts catalyst consisting of a halide of an element having at least two valences, is improved when maintaining constant at any time the molar ratio of the naphthalene compound to the acylating agent and that of the acylating agent to the Friedel Crafts catalyst within specific ranges.
