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,我们曾报道了溴化 In recent years, Huang Yaoyuan and other organic salts used in the original generation of Ye Lide and its use in organic synthesis, Ye Lide chemistry has been further developed, we will place arsonium ylide and carbonyl compounds, the reaction product of epoxy compounds or Olefins, Factors Affecting the Reaction Products In addition to the structure of arsonium ylides, the solvent effect tends to play a decisive role. In order to further investigate the reactivity of the semi-stable arsonium ylides, to find favorable reaction conditions and to explore the solvent effect, we have reported that bromination
