A mixture of 4-bromobenzenediazonium tetrafluoroborate (0.25 mmol), immobilized photocatalyst (5 mg, ∼3.6 μmol), and furan (1.0 mL) in solvent (2.0 mL) stirred under green LED at 30 °C for 2 h.
Experiment was carried out in the absence of photocatalyst.
Experiment was carried out without irradiation.
Without irradiation, in the absence of photocatalyst.
