In this thesis, multi-wall carbon nanotubeswas worked as a modified agent. The working electrode was a glassy carbon electrode or graphite electrode. A saturated calomel electrode and a platinum electrode were used as the reference and the auxiliary electrode respectively. Some pharmaceutics'electro-chemical behavior has been studied with great details. The main researches were summarized as follows: The acid-treated CNT was successfully dispersed into the DMF by using ultrasound technology.

考察了硫盐结构对反应的影响，当硫盐中碳-硫键位于樟脑骨架 endo 位置和碳-硫键位于 exo 位置时所得环丙烷化反应主产物的绝对构型相反。

For the stepwise mechanism, the ethylene molecule was firstly adsorbed at the Brnsted acid site via π-hydrogen bonding to form a stable complex, which then went through the protonation, leading to the formation of the ethoxide intermediate. Furthermore, the ethoxide reacted with the second ethylene molecule to form the butoxide product.
