Perfluoroalkylation of α-Methylstyrene Using Titanium Oxide as a Photocatalyst.
A redox system for fluoroalkylation with perfluoroalkyl iodide using TiO 2 as a photocatalyst was developed. Photoirradiation of perfluoroalkyl iodide and α-methylstyrene in CH 3 CN in the presence of TiO 2 and NaBF 4 gave α-fluoroalkylstyrene.
