Scope of the Copper-Catalyzed Trifluoromethylation Reaction of Alkyl Bromides via Metallophotoredox^a,b

`

^aPerformed with CuCl₂ (20 mol %), 8 (2 equiv), 4 (2 equiv), Na₂CO₃ (4 equiv), and with either 1 (1 mol %) or 17 (5 mol %) in MeCN or DMSO, respectively (see Supporting Information for full experimental details).

^bDue to the volatility of a number of products, yields are reported on the basis of ¹⁹F NMR analysis using PhCF₃ as an internal standard. Isolated yields are in parentheses.

^cPerformed with 17 in DMSO for 1 h.

^dPerformed with 1 in MeCN for 4 h.

^ePerformed with 17 in DMSO for 30 min.
