Efficient and general methods for the synthesis of amines remain in high demand in the chemical industry. Among the many known processes, catalytic hydrogenation is a cost-effective and industrially proven reaction and currently used to produce a wide array of such compounds. We report a homogeneous nickel catalyst for hydrogenative cross coupling of a range of aromatic, heteroaromatic, and aliphatic

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
