amino]-l-naphthalenesulfonate (1, X = 4-CH3):same procedure as that used for 1, X = 3,5-(CH3)2; yield, 1%. *H NMR (Me2SO-rf6) (ppm): NH, 10.56 (1 H, s), aromatic , 7.0-8.3 (10 H, m), CH3, 2.23 (3 H, s).
8-[(3-Methylphenyl)amino]-l-naphthalenesulfonate (1, X = 3-CH3): reaction, 72 h at 160 °C; purification, chromatography on silica (elution: benzene-methanol), crystallized three times from water; yield 12%.
A kinetic study on the reaction of ozone with a series of propargyl compounds has been performed. Absolute rate data are included for the reaction of propargyl chloride in CCI4 and propargyl acetate in a series of solvents of differing polarity. The absolute rate constants are relatively insensitive to solvent polarity. A relative rate study of several propargyl compounds in methylene dichloride has been made. The rates correlate well with the corresponding Taft substituent constant. From the linearity of the correlation and low p value, as well as the insensi-
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
