A synergistic strategy enables the selective synthesis of mono-N-methylated aliphaticprimaryamines, including deuterium-labelled drugs. This innovative approach combines an earth-abundant manganese catalyst with a weak base, resulting in a practical and sustainable protocol for mono-N-methylation. By effectively inhibiting the formation of formamide byproducts, it eliminates the need for external
