Zusammenfassung: | The solvolysis of p-substituted benzenesulfonyl chlorides $(substituents:p-H, p-Br, p-NO_2, p-OCH_3)$ in acetonitrile-water mixtures below 50 % of water content has been studied kinetically. Results show that Hammett plots give concaved curves but the mechanism is predominantly $S_N2$ and water acts both as nucleophile and general-base. 물함량 50% 이하의 아세토니트릴-물 혼합용매내에서의 염화벤젠술포닐의 $p-H, p-NO_2, p-Br, p-OCH_3$, 치환체들의 가용매분해를 반응속도론적으로 연구한 결과 Hammett 도시는 concave한 곡선들이나 $S-N2$성격이 압도적이었으며 물은 친핵제 뿐만 아니라 general base로도 작용하고 있음을 알았다. |
