Abstract

Substituent effects of leaving group in benzylarenesulfonates solvolysis have been carried out in 10∼50% water-acetone mixtures by electric conductivity method. Results of solvent effects, substituent effects and variable rate difference of water contents, show that $S_N1$ character almost predominates through the substituents, though p-MeO favors more or less $S_N2$ character in low water contents.

合成한 benzyl arenesulfonate의 離脫基의 置換基效果를 硏究하기 위하여 10 ∼ 15 vol. % 아세톤-물 混合溶媒속에서 溶媒分解速度를 電氣傳導法으로 測定하였다. 溶媒效果, 置換基效果 그리고 물 含量에 따른 速度變化를 檢討한 結果, 물含量이 적은 部分에서는 $p-OCH_3$는 $S_N2$性格이 다소 나타나나, 全置換基를 통해서 대체적으로 $S_N1$性格이 支配的인 反應임을 알 수 있었다.
