It has come to the authors attention that the experimental turnover frequencies (TOFs) were calculated incorrectly by using a second-order rate constant for the reaction instead of the first-order observed rate constant as defined in the original derivation.1, 2 The presented TOF values from re-analyzed experimental electrolysis data are shown below in an updated version of Table 1. These values should replace those in the originally published Table 1 and also replace their mention and discussion in the originally published Abstract and text.

These corrections do not affect the primary conclusions and mechanistic analysis presented in the published Communication. However, any discussion of the experimental TOF values in comparison to other previously reported systems no longer applies. Consistent with this, the revised Supporting Information document now shows the correct derivation of TOFs from electrolysis data, as well as a revised catalytic Tafel Plot in Figure S35.

勘误:介导的内球电子转移通过空间电子共轭诱导 CO2 的均匀还原

作者注意到,通过使用反应的二阶速率常数而不是原始推导中定义的一阶观察速率常数,错误地计算了实验转换频率 (TOF)。1, 2从重新分析的实验电解数据中呈现的 TOF 值显示在表 1 的更新版本中。这些值应替换最初发布的表 1 中的值,并替换它们在最初发布的摘要和文本中的提及和讨论.

这些更正不会影响已发表的通讯中提出的主要结论和机械分析。然而,与其他先前报道的系统相比,任何关于实验 TOF 值的讨论都不再适用。与此一致,修订后的支持信息文件现在显示了从电解数据中正确推导 TOF,以及图 S35 中修订的催化塔菲尔图。
