• 中文摘要： 研究3-苯基-4-乙醯基雪梨酮和3-(4'-乙醯基苯基)-4-乙醯基雪梨酮在玻碳電極之電化學還原現象; 包括酸度(B.R.緩衝液pH2.35-9.85)之變化,醋酸緩衝液,溶劑(DMF或EtOH)與不同支持電解質等對還原行為之影響。並將結果與汞電極及其他固態電極的比較。在醋酸緩衝液中沈積鎳和鋅離子於玻碳電極上。比較3-苯基-4-乙醯基雪梨酮和3-(4'-乙醯基苯基)-4-乙醯基雪梨酮於修飾電極之電化學還原現象,並討論電氫化之反應機構。
• 英文摘要： The electrochemical behaviors of 3-phenyl-4- acetylsydnone (I) and 3-(4'-acetylphenyl)-4-acetylsydnone(II) on glassy carbon electrode were investigated in a Britton-Robinson buffer (pH 2.35-9.85), acetate buffer and DMF or EtOH containing various supporting electrolytes. Those experimental results were compared with the data on mercury and other solid electrodes. The reduction of (I) and (II) at a glassy carbon electrode, i.e., on which Ni and Zn are deposited under the same conditions, was comparatively investigated in an acetate buffer solution. The mechanisms of the electrohydrogenations were also discussed.
