Over the past decade the organometallic chemistry of gold(III) has seen remarkable advances. This includes the synthesis of the first examples of several compound classes that have long been hypothesized as being part of catalytic cycles, such as gold(III) alkene, alkyne, CO and hydride complexes, and important catalysis-relevant reaction steps have at last been demonstrated for gold, like migratory insertion and β-H elimination reactions. Also, reaction pathways that were already known, for example the generation of gold(III) intermediates by oxidative addition and their reductive elimination, are much better understood. A deeper understanding of fundamental organometallic reactivity of gold(III) has revealed unexpected mechanistic avenues, which can open when the barriers for reactions that for other metals would be regarded as “standard” are too high. This review summarizes and evaluates these developments, together with applications of gold(III) in synthesis and catalysis, with emphasis on the mechanistic insight gained in these investigations.

金 (III) 化学的最新进展:结构、键合、反应性和在均相催化中的作用

在过去十年中,金 (III) 的有机金属化学取得了显着进展。这包括合成几个长期以来被假设为催化循环一部分的化合物类别的第一个例子,例如金 (III) 烯烃、炔烃、CO 和氢化物配合物,并且重要的催化相关反应步骤终于得到了证明了金,如迁移插入和 β-H 消除反应。此外,已知的反应途径,例如通过氧化加成和还原消除生成金 (III) 中间体,也得到了更好的理解。对金 (III) 的基本有机金属反应性的更深入理解揭示了意想不到的机理途径,当其他金属被视为“标准”的反应障碍太高时,它就会打开。这篇综述总结和评估了这些进展,以及金 (III) 在合成和催化中的应用,重点是在这些研究中获得的机理见解。
