Abstract

The development and design of new ligand systems with special donor properties has been essential for crucial advances made in main-group-element and transition-metal chemistry over the years. This Forum Article focuses on metalated ylides as novel ligand systems. These anionic congeners of bisylides possess likewise two lone pairs of electrons at the central carbon atom and can thus function as X,L-type ligands with strong donor abilities. This article highlights recent efforts in the isolation and application of metalated ylides with a focus on work from this laboratory. We summarize structural and electronic properties and their use in organic synthesis as well as main-group-element and transition-metal chemistry.

摘要

多年来,具有特殊给体性质的新型配体体系的开发与设计,对于主族元素化学和过渡金属化学取得的关键进展至关重要。这篇论坛文章聚焦于金属化叶立德作为新型配体体系。这些双叶立德的阴离子类似物在中心碳原子上同样具有两对孤对电子,因此可以作为具有强给体能力的X,L型配体。本文重点介绍了金属化叶立德的分离与应用方面的最新研究成果,尤其关注本实验室的工作。我们总结了其结构和电子性质,以及它们在有机合成以及主族元素化学和过渡金属化学中的应用。
