- 中文摘要: The rates of reaction of a series of substituted naphthoxides with 1-chloro-2,4-dinitrobenzene in methanol, and the pK/sub a/ values of the naphthols in 50% methanol have been measured. A linear free energy relationship applies well to these reactions. The rate constants are correlated with the pK/sub a/ values of the corresponding naphthols via the Bronsted equation giving a .beta. values of 0.94. A linear correlation between.DELTA.H/sup .dbldag./ and .DELTA.S/sup .dbldag./ is indicative of single mechanism. The nmr spectra of the substituted naphthols have been measured in DMSO-d/sub 6/.
