Kinetics of elimination reactions of 1 -chloro-1 -(4-methoxyphenyl)-2-phenylethane in acetonitrile

摘要

1-Chloro-1-(4-methoxyphenyl)-2-phenylethane undergoes dehydrochlorination in acetonitrile to give trans-p-methoxy stilbene by El mechanism.The presence of electron donating p-methoxy group and the delocalisation of charge throughout the structure proposes a stable cation.The mass law effect and special salt effect are characteristic for a reaction involving the stable cation and these effects have been reported for the first time in a pure El reaction.
