Abstract
N-methyl-2-amino-l-cyclopentene-l-dithiocarboxylic acid (N-CH3 acdc) 와 2-amino-l-cyclopentene-l-dithiomethyl ester (S-CH3 acdc)의 전기화학적 거동을 직류폴라로그래피, 순환전압전류법 및 조절전위 전기량법을 사용하여 dimethylformamide(DMF) 용매 중에서 조사하였다. N-CH3 acdc의 이합체는 + 0.98 V에서 2전자 산화반응을 거쳐 s가 한 원자 유리된 다섯 원자 고리를 형성하는 전극반응이 일어남을 알았다. 그러나, S-CH3 acdc의 경우에 있어서는 N-CH3 acdc화합물과는 달리 다섯원자 고리를 형성하지 않았으므로 N-CH3 acdc와는 다른 전극반응을 일으킴을 확인하였다.

The electrochemical behavior of N-methyl-2-amino-l-cyclopentene-l-dithiocarboxylic acid (N-CH3 acdc) and 2-amino-l-cyclopentene-l-dithiomethyl ester (S-CH3 acdc) in DMF have been investigated by the use of polarography, cyclic voltammetry and coulometry. The dimer of N-CH3 acdc is further oxidized at +0.98 V via 2-electron process to produce free sulfur atom and cyclization product. The ring formation between two dithio group occurs along with the elimination of one sulfur atom. The elimination of sulfur atom occurs via two electron oxidation process at + 0.98 V vs. Ag/AgCl electrode. However, the cyclization does not occur in the S-CH3 acdc.
