Abstract

Metallacycles, derivatives of carbocyclic compounds wherein a metal atom replaces at least one carbon center, have been a constant powerhouse in organic synthesis. While metallacycles of main-group, transition, and actinide metals have been extensively studied, those incorporating rare-earth (RE) elements (Sc, Y, and lanthanides) have remained elusive primarily due to synthetic challenges. Nevertheless, the electropositive character of these elements and the resulting polarization of RE–C bonds, along with the intrinsic synergistic effects within metallacycles, endow RE metallacycles with unique properties and a rich, yet largely untapped, reaction chemistry. In this Account, we present the development and applications of five-membered RE metallacycles.

迷人的五元稀土金属循环王国

金属环是碳环化合物的衍生物，其中金属原子取代了至少一个碳中心，在有机合成中一直是一个恒定的动力。虽然主族金属、过渡金属和锕系金属的金属循环已经被广泛研究，但那些含有稀土元素（Sc、Y和镧系元素）的金属循环仍然难以捉摸，主要是由于合成方面的挑战。然而，这些元素的正电特性和由此产生的RE - c键的极化，以及金属环内固有的协同效应，赋予了RE金属环独特的性质和丰富的，但在很大程度上尚未开发的反应化学。本文介绍了五元稀土金属循环的发展和应用。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
