Simple synthesis of CF3- and CF2H-spiroethers from aryl-fused cycloalkenylalkanols by photoredox catalysis has been developed. Modification of the fluoromethylating reagents and the photoredox catalysts leads to both CF3- and CF2H-spiroetherification. The present photocatalytic system allows us to access a variety of new anti-fluoromethylated spiroethers in a highly selective manner.
