机理研究和新反应的开发是相互交织的。这种相互依赖性为所有转化的发展带来了挑战和机遇,特别是对于那些使用贱金属催化剂的转化。与贵金属对应物相比,这些催化剂不太容易进行机理分析。然而,贱金属催化剂可以提供新的反应模式和发现机会。在这篇评论中,我们重点介绍了一个正在发展的领域:镍催化的立体选择性烷基交叉偶联反应。虽然相关催化循环的关键特征仍然模糊不清,但化学直觉和关键的机理实验为发现立体选择性转化提供了垫脚石。
Mechanistic investigation and new reaction development are intertwined. This interdependence presents challenges and opportunities in development of all transformations, particularly for those that employ base metal catalysts. In comparison to precious metal counterparts, these catalysts yield less easily to mechanistic analysis. However, base metal catalysts can provide new modes of reactivity and opportunities for discovery. In this commentary we highlight a developing field: nickel-catalyzed stereoselective alkyl cross-coupling reactions. While key features of the relevant catalytic cycles remain ambiguous, chemical intuition and key mechanistic experiments have provided the stepping stones for discovery of stereoselective transformations.
