Fluonnation enol acetates

Systems usually fluonnated by electropositive fluorine reagents include acti-vated alkenes (enol ethers, enol acetates, silyl enol ethers, and enamines), activated aromatic systems, certain slightly activated carbon-hydrogen bonds, and selected organometallics. 

Acyl hypofluorites react readily with enols, enol acetates, vinyl ethers, and enolates [39, 40, 41] (Table 2, entries 1-7) Steroidal enol acetates are also fluonnated smoothly [39] (equations 17-19)... 

Both enol acetates and enols are fluonnated by cesium fluoroxysulfate at room temperature in either acetonitrile or methylene chloride solutions (Table 2, entries 1,2 and 6)...
