/n

Versatile, reactive electrophilic fluorinating agent which can be used in water or organic solvents. A variety of substrates such as ketones: Tetrahedron Lett., 37, 3591 (1996), aromatics and enol ethers or enol esters, including steroidal derivatives, can be fluorinated successfully under mild conditions: Tetrahedron Lett., 40, 2673 (1999):

/n

Active methylene compounds (ß-diketonesandß-keto esters) are fluorinated in good yield in the presence of zinc chloride and imidazole or collidine. In the presence of water or alcohols, alkenes undergo hydroxy- or alkoxyfluorination to give fluorohydrin derivatives: Tetrahedron Lett., 36, 6769 (1995); 40, 2673 (1999).
