Reaction conditions: 0.25 mmol of bromobenzene, 0.31 mmol of 4-methylphenylboronic acid, 0.75 mmol of K2CO3, 30 mg catalyst (while the physically mixed samples Pd-ZnO and Pd-ZrO2 were tested, 15 mg of Pd-ZrO2, and 14 mg of Pd-ZnO were used in order to keep the same amount of Pd for each experiment), 5.0 mL of solvent (EtOH/H2O: 3/2), 25 °C, in the air. Reaction yields were determined by GC-MS, based on the bromobenzene, using n-octane as an internal standard.
