(7) Wheeler, AS; Mattox, WJ J. Am. Chem. SOC. 1933, 55, 686.(8) Thomson, RHJ Org. Chem. 1948, 13, 371. that this compound is an intermediate in the mechanism for the formation of 2 from I. The mechanism of formation of 3 may involve a rather complicated reaction sequence. de la Mareg has studied the chlorination of 1, 5-diacetoxynaphthalene in glacial acetic acid in great detail. In this reaction, the initial product is 5-acetoxy-2, 3, 4- ...
