Nucleophile의 親核性添加反應性을 정량적으로 연구하고자 3,4-methylenedioxy-$eta$ -nitrstyrene에 대해 우선 ethylmercaptan과 isopropylmercaptan을 써서 그외 添加反應速度常數를 측정한 결과 ethylmercaptide와 isopropylmercaptide ion에 대해 각각 $6.82{ imes}10^7M^{-2}$,$ sec^{-1}$, and $2.86{ imes}10^7M^{-2}$,$sec^{-1}$를 얻었으며 염기성 뿐만 아니라 산성 촉매속에서도 그의 반응메카니즘을 잘 설명할 수 있는 속도식도 구하였다.
In order to attempt the quantitative correlation of nucleophilic addition(not nucleopbilic substitution) reactivity of nucleophile, the addition constants of ethyl and isopropyl mercaptan to 3,4-methylenedioxy-$eta$-nitrostyrene were determined and found to be $6.82{ imes}10^7 $ and $2.86{ imes}10^7 M^{-2},;sec^{-1}$ respectively. From the rate equation obtained, the addition mechanism at basic media especially the complex addition mechanism at acidic media which has not been revealed can also be fully explained.
