Performed on a 0.5 mmol scale with alcohol (1.0 equiv), 2 (1.2 equiv), pyridine (1.2 equiv), tBuOMe (0.1 M); Ir(dF(OMe)ppy)2(5,5′(CF3)-bpy)PF6 (1 mol %), dMesSCF3 (1.5 equiv), TBACl (2 equiv), quinuclidine (1.6 equiv), DMSO (0.025 M), integrated photoreactor (450 nm, 100% light intensity). Assay yields were determined by 19F NMR analysis of the crude reaction mixture using 1,4-difluorobenzene as an internal standard. Isolated yields are in parentheses.
With Cu(terpy)Cl2 (10 mol %).
With Cu(terpy)Cl2 (5 mol %).
