Fluorine makes it possible: A cationic fluorine–gold species generated by fluorination of a low‐valence gold complex mediates the “functionalized hydration” of alkynes. A triple bond is used to install a carbonyl group and two new bonds on the α‐carbon atom, all occurring in one pot, under mild conditions and in very good yields (see scheme).

A library-friendly synthesis of alpha-substituted-alpha-fluoroketones through functionalized hydration of alkynes in one pot under mild conditions is reported. The ready availability of alkynes and organoboronic acids makes this reaction quite attractive. We also studied the key intermediate a fluorinated cationic gold species using in situ NMR spectroscopy and ESI-high resolution mass spectrometry. (C) 2011 Elsevier B.V. All rights reserved.
