摘要
研究了胺烷基二茂铁环钯化反应。探讨了反Cope准则的现象,阐明了胺组分的电子效应和空间结构、体系的酸碱度和体系的温域是决定生成环钯化产物的重要因素。
The effects of various factors, such as the electronic effect and volume of amines,the proportion and the reaction temperature, etc.were studied via a series of related experiments. We carried out a preliminary study on the abnormal phenomenon of Cope rule by which the cyclopallated complexes were got while the second amines were used as the substrates.We also found that acidity and temperature of the reaction system were important factors to form cyclopalladated complexes.
