Gram-scale reactions. Demonstrating the practical utility for the synthesis of selected N-methylamines in up to 10 g. Reaction conditions: 1–10 g nitroarenes; 5 mol% Fe2O3/NGr@C, 300 mg paraformaldehyde (10 mmol) and 1 mmol Na2CO3 for each 0.5 mmol nitroarenes; 40–200 mL DMSO-water (1:1); 130 °C; 30–40 h; isolated yields
