<p>The application provides a photochemical process for the chemoselective fluorination of an organic compound by combining a carbon-containing compound having an unactivated sp3 C-H bond with a reagent system comprised of a fluorinating agent, and a photocatalyst, in the presence of a light source. Provided as fluorinating agent is N-fluorobenzenesulfonimide (NFSI) or 1-chloromethy1-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) (Selectfluor™), as photocatalyst is tetrabutylammonium decatungstate (TBADT), and as light source is a 365 nm UV lamp. The reactions conditions result in the C-H bond being replaced by a C-F bond, to provide a fluorinated carbon-containing compound.</p> |
