The catalysis of precious metal phosphides in liquid-phase molecular transformations has rarely been explored. Herein, we reveal the remarkable performance of ruthenium phosphide nanoparticles supported on activated carbon (Ru2P/C) as a highly efficient heterogeneous catalyst for reductive amination of carbonyl compounds. Typically, Ru2P/C exhibited high activity for amination even under 1 bar of H2/NH3 mixed gas, in sharp contrast to the conventional Ru catalysts that require high H2 pressure (H2 2.5–40 bar) …
