Abstract

Substituent effects of benzyl substrates for the reaction of substituted benzyl(Z) arenesulfonate(X) with dimethylanilines in (Y) acetone at $35^{circ}$ were studied. The interactions between Z and Y disappeared when changed from electron withdrawing group to releasing group in benzyl substrates. The disappearance of interactions between Z and Y infers change of mechanism from $S_N2 to S_N1$ in substituent Z.

置換 benzyl (X)arensulfornate (Z)와 置換디메틸아닐린(Y)을 아세톤 容媒中에서 Menschatkin型 反應에 對한 벤질核의 置換基 效果를 檢討하였다. Z의 置換基가 電子끄는基에서 주는 基로 變할때 ZY 間에 存在하던 相互作用項이 消失되었다. ZY間의 相互作用項의 유무는 Z의 置換基 變化에 依한 $S_N2{\longrightarrow}S_N1$에의 機構의 變化에 對應된다고 생각된다.
