How is Trifluoroacetonitrile (CAS: 353-85-5) typically synthesized?

Trifluoroacetonitrile (CAS: 353-85-5) is typically synthesized by the radical addition of trifluoroacetic acid to acetonitrile. This reaction can be catalyzed by UV light or other initiators. The process is highly selective and generally yields a purifiable product. Other methods include the fluoride-mediated reaction of acetonitrile with trifluoroacetic anhydride, although this route is less common.
