In an N2 filled dry box, 8 mg (.023 mmol, 6 mol %) of 1, 70.7 mg (66 μl, 0.38 mmol) diphenylphosphine and 39.5 mg (43.5 μl, 0.38 mmol) of styrene was measured and mixed in 0.6 mL benzene-d6. This solution was transferred to an NMR tube. Initial 1 H and 31 P NMR spectra were obtained before placing the tube in a photoreactor containing a Rexim G23 UV-A (9W) lamp at ambient temperature. The temperature of the 360 nm photoreactor was measured to be 25-30 °C, depending on how long it had been in use.
