Standard conditions: 1 (1.0 equiv., 0.50 mmol), 8a–j (3.0 equiv., 1.5 mmol), DCB (0.25 M, 2.0 mL), Co(acac)2 (10 mol%, 0.050 mmol), temperature as indicated, for 24 h under an O2 atmosphere. The selectivity of alcohol:ketone was determined by 19F NMR analysis of the crude reaction mixture and is reported in parentheses. Yields of pure isolated product represent the average of 2 runs.
