a Schematic representation of catalyst preparation; (b) investigating the effect of different ligands; (c) testing the activity of different metal-based materials; (d) investigating the effect of different solvents. e Stability and recycling tests of Co-L1@NC-800. Reaction conditions: 0.3 mmol 2-phenoxy-1-phenylethanol, 0.6 mmol aniline, 0.15 mmol K3PO4, 40 mg catalyst (4.5–5 mol% metal), 5 bar O2, 3 mL H2O, 140 °C, 20 h, the conversion and yields were calculated by GC based on 1 with mesitylene as internal standard. Reaction conditions for (e): 0.6 mmol 2-phenoxy-1-phenylethanol, 1.2 mmol aniline, 0.3 mmol K3PO4, 80 mg Co-L1@NC-800 (4.52 mol% Co), 5 bar O2, 5 mL solvent H2O, 140 °C, 7 h.
