Abstract
Substitution reactions of 13 kinds of compounds having a substituent on m-or p-position of benzene ring of 2, 4-bis (anilino)-6-chloro-S-triazine with benzylamine in tetrahydrofuran solvent have been investigated. The measurements of the Reactionrates indicated that these reactions agreed well with be'simple second-oder kinetics and were represented to SN 2 process.As to the reactivity of these derivatives, it was found that the relation between the reaction velocity and the substituent in benzene ring followed the Hammett's rule well when the triazinylamino group was considered as a side chain of both benzene rings. It was also clarified that the effectof substituent was mainly due to its polar effect.
