A Trick to Fluorinate Grignards

Knochel’s group has shown that you can fluorinate Grignard reagents without decomposition via single-electron transfer reactivity (SET) by a simple solvent switch from THF to DCM. A common way to prepare aryl fluorides is through lithium-halogen exchange, followed by trapping with N-fluorosulfonimide (NFSI).  This isn’t always viable, as the alkyllithium Read more…
