在Suzuki-Miyaura反应期间,醛和酮(而不是酯或酰胺)与Ni 0的能量有利的配位可以导致精确的选择性和增强的反应性,或者抑制反应。C-X键连接到与醛或酮相同的π-体系的芳基卤化物发生意外的快速氧化加成[Ni(COD)(dppf)](1),并在竞争反应期间选择性交叉偶联。当醛和酮以外源添加剂的形式存在时,交叉偶联反应被抑制到一定程度,该程度取决于侧羰基与Ni 0的配位强度。这项工作推进了我们对常见官能团如何与Ni 0催化剂相互作用以及这些相互作用如何影响学术界和工业界的主力催化反应的理解。醛和酮可以对镍催化的反应具有有益或有害的影响。当存在于芳基卤上时,可以实现优异的位点选择性;当作为添加剂存在时,它们抑制反应。
The energetically-favorable coordination of aldehydes and ketones – but not esters or amides – to Ni0 during Suzuki–Miyaura reactions can lead either to exquisite selectivity and enhanced reactivity, or to inhibition of the reaction. Aryl halides where the C–X bond is connected to the same π-system as an aldehyde or ketone undergo unexpectedly rapid oxidative addition to [Ni(COD)(dppf)] (1), and are selectively cross-coupled during competition reactions. When aldehydes and ketones are present in the form of exogenous additives, the cross-coupling reaction is inhibited to an extent that depends on the strength of the coordination of the pendant carbonyl group to Ni0. This work advances our understanding of how common functional groups interact with Ni0 catalysts and how these interactions affect workhorse catalytic reactions in academia and industry. Aldehydes and ketones can have beneficial or detrimental effects on nickel-catalysed reactions. When present on the aryl halide, excellent site-selectivity can be achieved; when present as additives, they inhibit the reaction.
