More cleavage : The complex [(Cp*Ru) 3 (μ 3 ‐H) 2 (μ‐H) 3 ] (Cp*=η 5 ‐C 5 Me 5 ) promotes NH bond cleavage of ammonia to yield the mono‐μ 3 ‐imido complex [(Cp*Ru) 3 (μ 3 ‐NH)(μ‐H) 3 ] ( 2 ), probably via μ‐amido complex [(Cp*Ru) 3 (μ‐NH 2 )(μ‐H) 4 ]. Introduction of a triply bridging oxo ligand into the Ru 3 core (→ 1 ) makes the reaction kinetically and thermodynamically favorable and gives 2 within 1 h at 80 °C.
