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 (<i>Z</i>)-fluorinated hydrazones. Cyclic voltammetry and associated mechanistic investigations were conducted to provide insight into the radical mechanistic pathway.
