    摘要: 本研究係利用極譜儀研究五種3一取代基一4一甲醛基雪梨酮在滴汞電極(dropping mercury electrode )之還原現象 ; 包括酸度,反應物濃度,溶劑與支持電解質等對還原行為之影響。並由半波電位,極限電流與pH值之關係,探討在電極的反應機構。由極譜法與紫外線吸收光譜法證實3一取代基一4一甲醛基雪梨酮的還原電位符合修飾過的Hammett式。
    The reducing behavious of five 3-substituted-y-formylsydnones were studied with dropping mercury electrode including the influences of acidity, concentration, solvent and supporting electolyte. And the possible reaction mechanisms were discussed by the relations of half-wave potentials, limiting current and pH-values. According to the results of the polarographic and UV spectrophotometric methods,the reducing potentials of 3-substituted-4-formylsydnones obey the modified Hammett equation.
