Ketone to Difluoro








Common Conditions:


DAST

DAST is a nucleophilic fluorinating reagent. DAST is not as reactive towards ketones as it is with alcohols but conditions are still typically mild (0 C to RT). DAST can be unstable if heated (possible detonation at >90 C). The solvent of choice is usually DCM.[1][2][3]





Deoxo-Fluor

Deoxo-Fluor is a nucleophilic fluorinating reagent with similar and, in some cases, superior reactivity to DAST. Deoxo-Fluor is more thermally stable than DAST.[3]
