^aConditions: 9a–9f (0.1 mmol), diisopropylamine (DIPEA) (0.2 mmol), 1,4-cyclohexadiene (1,4-CHD) (0.2 mmol), and UiO-68[Au1]_4.5% (5 mg) in a MeCN/MeOH mixture (1 : 1, 1 mL each) at room temperature under argon and 410 nm irradiation for 0.5–6 h; conversions and product yields were determined by ¹H NMR analysis from the crude product using chlorodiphenylmethane as an internal standard.
