Abstract
9종류의 m-또는 p-치환 phenacyl bromide와 quinoline을 같은 몰 비로 메탄올 용매하에서 반응시켜 반응속도를 전기 전도도법으로 측정하였다. 이들 반응은 SN2과정에서 따라 진행하며 전자 주는 기나 전자 끄는 기가 모두 반응속도를 촉진하였으며 이 사실을 설명할 수 있는 반응메카니즘을 제시하였다. 또 이 반응에 수반하는 열역학적 parameter도 구하였다.

Rates of reactions of nine m-or p-substituted phenacyl bromides with quinoline in methanol were measured by an electric conductivity method. These reactions were found to proceed through an SN2 path and were accelerated by both electron-donating and electron-withdrawing substituents. A plausible reaction mechanism for this observation was proposed. Some activation parameters for these reactions were also calculated.
