Fluorocarbanion Chemistry. A Versatile Synthesis of Functionalized Fluoro Ketones

Article abstract of DOI:10.1021/jo00353a009

Fluorocarbanions generated by the addition of an anion to a fluoro olefin can be trapped by fluoro esters, thereby providing a versatile, one-step synthesis of functionalized fluoro ketones.The most efficient anions include CN^-, N3^-, C6H5O^-, RO^-, and RS^-.The reaction has been extended in one case to prepare a sulfinate ester.
