In order to clarify the effect of X on the reactivity of active chlorine atom in chloro-S-triazine derivatives having substituent groups, the reaction between A-type chloro-S-triazine derivative, and aniline has been investigated.The result of comparison of reaction velocities indicated that the reactivity of A was decreased in the order of The effect of X was mainly due to its polar effect, this was considered to be transmitted to the reacting position of s -triazine nucleus through an oxygen atom. Accordingly, it was clarified that an electron-attractive group X had a tendency to proceed the reaction of aniline easily while the X having an electron-donating property retarded the reaction.Also, the reaction between A (X=H) and type aniline substituent has been investigated.It was found that the reactivity of aniline was decreased in the order of Thus, there was a regularity that the electron-donating group in A caused an increase in the reactivity of aniline while the electron-attractive group decreased the reactivity.
