Disproportionation and comproportionation reactions have become increasingly important electron transfer events in organometallic chemistry and catalysis. The renewed interest in these reactions is in part attributed to the improved understanding of first-row metals and their ability to occupy odd and even oxidation states. Disproportionation and comproportionation reactions enable metal complexes to shuttle between various oxidation states, a matter of utmost relevance for controlling the speciation and catalytic turnover. In addition, these reactions have a direct impact in the thermodynamic and kinetic stability of the corresponding metal complexes. This review covers the relevance and impact of these processes in electron transfer reactions and provides valuable information about their non-negligible influence in Ni- and Cu-catalysed transformations.
歧化反应和反歧化反应已成为有机金属化学和催化中日益重要的电子转移事件。对这些反应重新产生兴趣部分归因于对第一排金属及其占据奇数和偶数氧化态能力的更好理解。歧化反应和反歧化反应使金属配合物能够在各种氧化态之间穿梭,这对于控制物种形成和催化周转至关重要。此外,这些反应对相应金属配合物的热力学和动力学稳定性有直接影响。本综述涵盖了这些过程在电子转移反应中的相关性和影响,并提供了有关它们在镍和铜催化转化中不可忽视的影响的有价值信息。
