Electrochemical Direct C–H Fluorination of Hydrazones

In this work, we present a mild and efficient electrochemical method for the direct C–H fluorination of aldehyde hydrazones using KF as an inexpensive and readily available fluorine source. This direct electrochemical approach could tolerate various functional groups, affording a diverse collection of (Z)-fluorinated hydrazones. Cyclic voltammetry and associated mechanistic investigations were conducted to provide insight into the radical mechanistic pathway.
