Voltammetric Studies on the Reduction Potentials of Perfluoroalkyl Halides and Their Analogous Compounds (Supporting Information)

Photocatalytic single-electron transfer (SET) reactions involving perfluoroalkyl halides play a crucial role in synthetic organic chemistry. However, the electrochemical data for these compounds, which are essential in the discussion of the SET process, are missing. In this study, the electrochemical reduction potentials of perfluoroalkyl halides, alkyl halides, and other analogous compounds were investigated in 0.1 M Bu4NPF6/CH3CN using Ag, Pt, and glassy carbon electrodes. The Ag electrode showed remarkable catalytic properties and a positive reduction peak shift during the reduction reaction; this indicates that the Ag electrode is suitable for estimating the electrochemical potential of the SET process. This study provides a comprehensive dataset for the electrochemical measurements of perfluoroalkyl and alkyl halides, which will help synthetic organic chemists select appropriate reaction systems for these compounds.

过氟烷基卤化物参与的催化单电子转移（SET）反应在合成有机化学中发挥着至关重要的作用。然而，这些化合物在SET过程讨论中至关重要的电化学数据却缺失。在本研究中，我们采用Ag、Pt和玻璃碳电极，在0.1 M Bu4NPF6/CH3CN溶液中对过氟烷基卤化物、烷基卤化物以及其他类似化合物的电化学还原电位进行了探究。Ag电极在还原反应中表现出卓越的催化性能，并呈现出正向还原峰位偏移；这表明Ag电极适用于估算SET过程的电化学势。本研究为过氟烷基和烷基卤化物的电化学测量提供了一个全面的数据集，这将有助于合成有机化学家选择适用于这些化合物的适宜反应体系。
