^aReaction conditions: arylboronic acid (0.1 mmol), diisopropylamine (0.4 mmol) and 2c (0.5 μmol) in DMF (1.5 mL), O₂ bubbling, xenon lamp (>400 nm).

^bNo 2c added.

^cDetermined by ¹H NMR analysis of the crude reaction mixture.

^dDetermined by ¹H NMR analysis using 1,1-diphenylethylene as an internal standard.

^en.d. = not determined.
