Rate constants for the reactions of aniline with 6- and 3-substituted 2-naphthoyl chlorides and 6- and 4-substituted 1-naphthoyl chlorides have been measured at several temperatures in benzene solution.The Hammett equation applies very well in all these cases.The p values for the reaction with 6-substituted 2-naphthoyl chlorides are 1.38, 1.31 and 1.26 at 30, 35 and 40 deg C respectively and those for the reaction with 6- and 4-substituted 1-naphthoyl chlorides are 1.28, 1.24 and 1.19 at 30, 35 and 40 deg C respectively.The reaction of 3-substituted 2-naphthoyl chlo-rides also adheres to the Hammett equation with ?p constants, giving a p value of 1.55 at 30 deg C.
