摘要: 近年来,黄耀曾等应用有机鉮盐原地生成叶立德并将它用于有机合成,使叶立德化学有了更大的发展,我们将原地生成的胂叶立德与羰基化合物反应,产物为环氧化合物或烯烃,影响反应产物的因素除胂叶立德的结构外,溶剂效应往往起决定作用,为了进一步研究半稳定胂叶立德的反应性能,寻求有利的反应条件,探索溶剂效应。

Abstract: This paper presents the reaction of arsonium salts (1,2) with aromatic aldehydes in the two phase system of C6H6(CH2Cl2)-50% NaOH(aq.) at room temperature to afford frons-olefinic derivatives (3a-i), and the yields were 86%-94%. We also found that the solvent effects exist in the phase transfer reaction between (2) with the aromatic aldehydes.

Key words: Solvent effects, Arsonium salts, Phase transfer
