Olefins and alkynes are ubiquitous in transition-metal catalysis, whether introduced by the substrate, the catalyst, or as an additive. Whereas the impact of metals and ligands is relatively well understood, the effects of olefins in these reactions are generally underappreciated, even though numerous examples of olefins influencing the outcome of a reaction, through increased activity, stability, or selectivity, have been reported. This Review provides an overview of the interaction of olefins with transition metals and documents examples of olefins influencing the outcome of catalytic reactions, in particular cross-coupling reactions. It should thus provide a basis for the improved understanding and further utilization of olefin and alkyne effects in transition-metal-catalyzed reactions.
烯烃和炔烃在过渡金属催化中无处不在，无论是由底物、催化剂引入，还是作为添加剂。虽然人们对金属和配体的影响相对了解较多，但烯烃在这些反应中的作用通常未得到充分重视，尽管已有许多报道表明烯烃通过提高活性、稳定性或选择性来影响反应结果。本综述概述了烯烃与过渡金属的相互作用，并列举了烯烃影响催化反应结果的实例，特别是交叉偶联反应。因此，它应为更好地理解和进一步利用烯烃和炔烃在过渡金属催化反应中的作用提供基础。
