Abstract

cis-and trans-2-butenedialdioximes are synthesized via 2-butenedials, very unstable precursors, and the conformation of the cis-isomer of those compounds is determined by the NMR spectra of 1,4-dideutero-and 1-deutero-cis-2-butenedialdioximes; it is certain that the conformation has an unsymmetrical structure as shown below.

매우 不安定한 中間生成物인 2-butenedial을 거쳐서 cis- 및 trans-2-utenedialdioxime을 合成하고, cis-이성질체의 형태(conformation)를 決定하였다. 1,4-dideutero- 및 1-deutero-cis-2-butenedialdioxime의 NMR 解析에 依해서 目的物의 형태가 아래와 같은 非對稱構造임을 밝혔다.
