The ability of Lewis acids to coordinate to transition metals as σ-acceptor ligands was recognized as early as in the 1970's, but so-called Z-type ligands remained curiosities until the early 2000's. Over the last decade, significant progress has been made in this area, especially via the incorporation of Lewis acid moieties into multidentate, ambiphilic ligands. Our understanding of the nature and influence of TM → Z interactions has considerably improved and the scope of Lewis acids susceptible to behave as σ-acceptor ligands has been significantly extended. This feature article summarizes these recent achievements.
早在 20 世纪 70 年代,人们就已经认识到路易斯酸作为 σ-接受体配体与过渡金属配位的能力,但直到 21 世纪初,所谓的 Z 型配体仍然是个谜。在过去的十年中,这一领域取得了重大进展,特别是通过将路易斯酸部分引入多齿、两性配体。我们对 TM → Z 相互作用的性质和影响的理解有了很大的提高,并且能够作为 σ-接受体配体的路易斯酸的范围也得到了显著扩展。本文总结了这些最新的研究成果。
