A 10 mL oven-dried microwave vial was cycled into a glovebox. To this was added 6 (101 L, 0.7 mmol, 1 eq.), Pd(OAc)2 (15.7 mg, 0.07 mmol, 0.1 eq.), Xantphos (81.0 mg, 0.14 mmol, 0.2 eq.), Cs2CO3 (456.1 mg, 1.4 mmol, 2 eq.) and benzene (5 mL). The vial was capped, removed from the glovebox and stirred in a oil bath set to 60 o C. After stirring for 1 h, stirring was stopped and insolubles were allowed to settle before 50 L of the solution was removed and quenched into 1 mL of an n-dodecane solution (6.5 mg n-dodecane in 15 mL of EtOAc, 0.433 mg per sample). The reaction flask was then placed under irradiation for 30 min after which another 50 L aliquot was removed and quenched. The on/off cycle was repeated for the time intervals given below. Each quenched aliquot was analysed by GC-FID to obtain yields of each product, provided below. Columns in blue indicate intervals of irradiation. The period after 24 hours compares well to the standard assay reaction (Table , entry 8), but has been excluded from graphs for clarity of the steps.
