To elucidate the mode of hydrogen–hydrogen bond cleavage at transition metal sites that cooperate with a heteroatom, the hydrogenation of trinuclear μ 3 ‐imido complex (Cp*Ru) 3 (μ 3 ‐NH)(μ‐H) 3 (Cp* = η 5 ‐C 5 Me 5 ) ( 1 ) with deuterium was carried out. The percentage of deuterium content in the amido ligand of (Cp*Ru) 3 (μ‐NH 2 )(μ‐H) 4 ( 2 ), which was generated as an intermediate in the reaction of 1 with dihydrogen, proved that hydrogenation of 1 to 2 proceeded through homolytic cleavage of dihydrogen.(© Wiley‐VCH Verlag GmbH & Co.
