Dual Activation of Organoboron for the Ion-Pair-Mediated Synthesis of Hindered Alkyl Fluorides

A novel electrochemical approach for the synthesis of hindered alkyl fluorides has been developed. The protocol grants access to a diverse array of tertiary and secondary alkyl fluorides using readily attainable organoboron precursors under mild conditions. The efficiency of the system stems from the dual activation of the redox-active borate intermediate, providing both electrophilic and nucleophilic reaction partners in the form of an internally generated ion pair.
