Abstract Synthesis of cyanofluoromethylated ketones is discussed. The Michael addition of α‐cyano‐α‐fluoromethyl anion species to α,β‐unsaturatedketones is investigated.

An efficient synthesis of a variety of 2-arylacetonitriles containing a fluorinated stereogenic center through organo-catalyzed Michael addition reaction of 2-fluoro-2-arylacetonitriles has been developed. This protocol uses a cheap organocatalyst (DBU) and has a broad substrate scope: α, β-unsaturated ketones, esters, nitriles and sulfones were all successfully reacted. Importantly, water proved to
