  Abstract

반양성자성 용매인 dimethylsulfoxide중에서 p-nitrobenzeneazoresororcinol<4n-BAR>에 대하여 직류 폴라로그래피적 거동을 조사하였다. 0.05M NaClO4의 DMSO용매중에서 4n-BAR은 1전자 2단계의 환원과정을 거쳐 hydrazo기를 포함하는 화합물로 환원된다. 환원반응의 중간 생성물은 비교적 반양성자성 용매 속에서 안정하였다. 각 단계의 환원전류는 확산지배적이었으며 일부 반응전류도 포함되었다. 산을 첨가함에 따라서 2개의 환원파가 하나로 합치되며 [acid]/[reductant]의 몰 (M)비가 M = 2인 조건에서 가전위(-E)에 대해 log (id-i) (Mid / 2-i) / i의 가역성은 1전자 2단계 환원반응이고 비가역적이었다. The direct current polarographic behavior of 4n-BAR in dimethylsulfoxide as an aprotic solvent have been investigated. The reduction of 4n-BAR in 0.05M sodium perchlorate solution proceeds along two one-electron steps to give the corresponding compound containing hydrazo groups, each reduction wave was considerably diffusion controlled and irreversible. By addition of acid HAc to 4n-BAR in DMSO solvent, the two reduction waves have coalesced into one in the condition M ≥ mole ratio, acid/reductant(M = 2), the slope of log (id-i) (Mid / 2-i) / i vs. (-E) is irreversible along one-electron steps reduction waves.
