1，2－（2，4，6－三硝基）苯基乙烷溴氧化过程的~1HNMR研究

STUDY ON THE MECHANISM OF BROMINE OXIDATON OF1,2-BIS(2.4,6-TRINITRO)PHENYLETHNE WITH ￣1HNMR SPECTRA

由１，２－二（２，４，６－三硝基）苯基乙烷经氧化脱氢反应可合成２，２′，４，４′，６，６′－硝基芪，若反应介质中有水存在，产物的收率明显下降。用￣１ＨＮＭＲ跟踪了在含水吡啶中１，２－二（２，４，６－三硝基）苯基乙烷溴氧化的反应过程，结果表明，反应物经过中间体２，４，６－三硝基苯甲醛被氧化成２，４，６－三硝基苯甲酸。

Abstract Hexanitrosilbene(HNS)could be sythesized by dehydrogenation of 1,2-bid(2,4,6- trinitro)phenylethane(DPE).Ifthe medium has little water, the yild of product HNS will decreace apparently. In this paper, the mechanism of bromine oxidation ofDPE is sttidied by using￣1HNMR. As a result,in medium pyridine containing a little water.DPE is oxidated into 2,4,6-trinitrobenzenecarbonic acid with intermeedate 2,4,6-trin-trobenzaldehyde.
