Substituted isoxazolidinium salts react with LiAlH4 to yield ring opened hydroxylamines. The novel bimolecular reaction mechanism has been investigated by deuterium labelling and the structure of the products ascertained by spectroscopic methods with the aid of the MIKE technique. The overall process can be defined as a ring-opening substitution, which is controlled by steric and conformational factors
取代的异恶唑烷鎓盐与LiAlH 4反应生成开环的羟胺。通过氘标记研究了新型的双分子反应机理,并借助MIKE技术通过光谱法确定了产物的结构。整个过程可以定义为开环取代,其受空间和构象因素控制,这些因素倾向于防止盐类发生霍夫曼效应。
