Any old iron? Iron catalysts based on the widely available diphosphine ligand bis(diphenylphosphino)ethane have not previously fared particularly well in iron‐catalyzed cross‐coupling processes. However, this turns out not to be due to any inherently poor performance associated with the ligand, but rather the need to form a bis‐chelate complex, either before or during the formation of an active FeI
有旧铁吗?以前,基于二膦配体双(二苯基膦基)乙烷的铁催化剂在铁催化的交叉偶联过程中表现不佳。然而,事实证明,这并不是由于与配体有关的固有性能较差,而是由于在形成活性Fe I物种之前或之中需要形成双螯合物。
