Abstract

Nucleophilic substitution reactions between Alkanesulfonylchlorides and p-substituted anilines in methanol-acetonitrile mixture have been studied kinetically. Reactivities of substrates, substituent effects of nucleophile and solvent effects indicate that the studied reaction proceeds via $S_N2$. The kinetic results show that transition state of the reaction between i-PSC and anilines becomes looser as the composition of methanol increases.

염화 알칸술포닐과 파라 치환된 아닐린간의 친핵성 치환반응을 메탄올-아세토니트릴 혼합용매하에서 연구하였다. 기질의 반응성, 친핵체의 치환기효과 및 용매효과로 부터 반응 메카니즘이 $S_N2$임을 알았다. i-PSC의 경우 메탄올 조성이 커짐에 따라 전이상태가 더 loose해 짐을 알았다.
