applied as an organophotocatalyst for the visible-light-induced trifluoromethylation of unactivated alkenes with CF3I. The mild reaction conditions tolerated a variety of functional groups, and the reaction could be extended to perfluoroalkylations with C3F7I and C4F9I. Mechanistic studies revealed that the photoredox catalysis involves an oxidative quenching pathway.
Photochemistry of Epoxynaphthoquinones. 8. Endo-Stereoselective Photocycloaddition of 2,3-Epoxy-2,3-dihydro-2,3-dimethyl-1,4-naphthoquinone to Olefins Containing Amide Group
Irradiation of a benzene solution of 2,3-epoxy-2,3-dihydro-2,3-dimethyl-1,4-naphthoquinone with olefins containing amide group, i.e., N-substituted acrylamides and N-allylcarboxamides predominantly gave the endo-cycloadducts. Upon further irradiation, the cycloadducts underwent photorearrangement to give spirophthalides and alkylidenephthalides.

iodoperfluoroalkylation of unactivated terminal alkenes and alkynes was explored. This process was found to be effective for the simultaneous introduction of iodide and various perfluoroalkyl groups (including difluoroacetate) to alkenes and alkynes possessing a variety of functional groups. A possible reaction mechanism is proposed. This reaction provides a new, metal-free, green method for the synthesis of perfluoroalkylated
