Time evolution of the N-methylation and N,N-dimethylation of aniline by Pd47Ag53 catalysts supported on Fe3O4/N-rGO. Reaction conditions: 140 °C, 0.1 mmol aniline, 1.2 mol% Pd, 30 equivalents formic acid, 2 ml DCM. Conversions and yields were determined by gas chromatography (GC), using n-hexadecane as an internal standard.
