摘要: 我们对酮肟中间体及肟醚类拟除虫菊酯[1]进行了分析。经核磁共振证明,酮肟中间体在生成肟醚南反应过程中其立体构型木发生变化。目前分离酮肟立体异构物的工作报道较少。我们通过薄层色谱对不同取代的具有活性的几种酮肟异构体的分离进行了探讨。

Abstract: The TLC separation of the geometric isomers of alkyl aryl ketone oximes which are the intermediates in the synthesis of a new group of pyrethroidlike alkylaryl ketone oxime o-ethers (the general structure is <这里有图片19880921-963-1.gif> ) has been investigated. The optimal conditions and the results for the E/Z separation of six different substituted phenyl isopropyl ketone oximes are given. The dependence of the three thin layer chromatographic parameters, Rf, ΔRf and α, on varying ratio of the TLCmobile phase ha been studied and the effect of the activity of absorbent on the separation is discussed.
