尽管金属金(Au)在流行文化中普遍存在，但它在均相催化中的应用直到最近才得到广泛的研究。在过去的十年中，特别是自2004年以来，在开发高效和选择性的金催化转化方面取得了很大进展，这一不断增长的领域的各个方面的大量综述就是明证。哈什米撰写了一系列全面的评论，概述了金催化反应发展的进展，1一些更有重点的评论进一步洞察了金催化的特定方面。对已发表的关于Au催化的各种观点的简要回顾有助于理解这篇化学评论文章的背景。在均相Au催化剂上开发的绝大多数反应都利用了Au作为亲电体激活碳-碳π-键的倾向。金已被认为是一种极温和的、相对亲碳的Lewis酸，并对通过激活不饱和碳-碳键进行的一系列新开发的反应进行了专业的综述。2对金的催化作用进行了进一步的综述和重点介绍，重点介绍了几类特殊的合成反应。对Au催化的烯炔环异构化反应有一篇很好的综合综述。3更侧重于炔烃的氢芳基化，4 CC多键的氢胺化，5以及氧代炔6和炔丙酸酯的反应7，对均相金催化的进展和未来的发展方向提供了有价值的前景。大多数关于金催化的综述侧重于在合成用途方面的广泛或具体的进展。最近，我们有
Despite the ubiquity of metallic gold (Au) in popular culture, its deployment in homogeneous catalysis has only recently undergone widespread investigation. In the past decade, and especially since 2004, great progress has been made in developing efficient and selective Au-catalyzed transformations, as evidenced by the prodigious number of reviews available on various aspects of this growing field. Hashmi has written a series of comprehensive reviews outlining the progression of Au-catalyzed reaction development, 1 and a number of more focused reviews provide further insight into particular aspects of Au catalysis. A brief metareview of the available range of perspectives published on Au catalysis helps to put this Chemical ReViews article in context.The vast majority of reactions developed with homogeneous Au catalysts have exploited the propensity of Au to activate carbon-carbon π-bonds as electrophiles. Gold has come to be regarded as an exceedingly mild, relatively carbophilic Lewis acid, and the broad array of newly developed reactions proceeding by activation of unsaturated carbon-carbon bonds has been expertly reviewed. 2 Further reviews and highlights on Au catalysis focus on particular classes of synthetic reactions. An excellent comprehensive review of Au-catalyzed enyne cycloisomerizations is available. 3 Even more focused highlights on hydroarylation of alkynes, 4 hydroamination of CC multiple bonds, 5 and reactions of oxo-alkynes6 and propargylic esters7 provide valuable perspectives on progress and future directions in the development of homogeneous Au catalysis. Most of the reviews on Au catalysis emphasize broad or specific advances in synthetic utility. Recently, we have
