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

α-Fluorophenylacetonitriles (3) are readily prepared by the treatment of the corresponding benzaldehyde cyanohydrin trimethylsilylethers (2) with diethylaminosulfur trifluoride (DAST). This method for the introduction of fluorine alpha to a cyano group is also applicable to the cyanohydrin trimethylsilylethers of aromatic ketones. Diborane reduction of the α-fluorophenylacetonitriles (3) yields 2-
