氮杂环卡宾钯催化C-S键断裂性能研究

The Preparation of Acenaphthoimidazolylidene Palladium Catalysts and Their Performance in the Activation of Inert C-S Bond

本文通过苊并咪唑氮杂环卡宾催化惰性C-S键的活化反应,成功实现了C-S/C-N偶联反应。经过条件优化后,可在温和条件下实现硫醚的高效转化,各种电子效应、位阻效应以及杂环底物均能很好地兼容,并以良好的产率得到相应的芳胺类化合物,为有机物脱硫奠定基础。

In this paper,the C-S/C-N coupling reaction was successfully realized by the activation of inert C-S bonds catalyzed by acenaphthoimidazolylidene palladium catalyst.After the optimization of reaction conditions,the efficient conversion of thioethers could be realized under mild conditions.Various substrates with different electronic effects,steric effects and heterocyclic substrates could be well tolerated in this catalytic system,and the corresponding aromatic amines could be obtained in good yields.This process would lay the foundation for the highly concerned desulfurization of organic compounds.
