The gaseous small molecules, CO and NO, play important roles in climate change and ozone layer depletion, and they hold promise as underutilized reagents and chemical feedstocks. However, productive transformations of these heteroallenes are difficult to achieve because of their inertness. In nature, these gases are cycled through ecological systems by metalloenzymes featuring multimetallic active sites that employ cooperative mechanisms. Thus, cooperative bimetallic chemistry is an important strategy for synthetic systems, as well. In this Perspective, recent advances (since 2010) in cooperative activation of CO and NO are reviewed, including examples involving s-block, p-block, d-block, and f-block metals and different combinations thereof.
气体小分子 CO 和 NO 在气候变化和臭氧层消耗中发挥着重要作用，它们作为未充分利用的试剂和化学原料具有很大的应用潜力。然而，由于这些杂烯的惰性，很难实现它们的有效转化。在自然界中，这些气体通过含有多金属活性位点的金属酶在生态系统中循环，这些酶采用协同机制。因此，协同双金属化学也是合成系统的一个重要策略。在这篇观点文章中，综述了自 2010 年以来 CO 和 NO 协同活化方面的最新进展，包括涉及 s 区、p 区、d 区和 f 区金属以及它们不同组合的例子。
