The combo pack: Copper‐catalyzed trifluoromethylation of alkenes bearing an allylic proton combined with CCbondformation affords the title compounds in good to high yields (see scheme). The reactions are faster than allylic trifluoromethylation, especially in 1,4‐dioxane. A unique 1,6‐oxytrifluoromethylation occurred instead of an anticipated seven‐membered ring forming carbotrifluoromethylation

Synthesis of Ketonylated Carbocycles: Synthesis of ketonylated fused six- and five-membered carbocycles through an excited-state copper-catalyzed radical carbo-aroylation of unactivatedalkenes. Preliminary mechanistic studies suggest a reaction pathway involving photoexcited copper catalyst, a single electron transfer (SET), radical aroylation of unactivatedalkenes, radical cyclization, and re-aromatization
