Dynamics of H-atom exchange in stable cis-dihydrogen/hydride complexes of ruthenium(ii) bearing phosphine and N-N bidentate ligands

Synthesis and characterization of cis,trans-[RuH(η2-H 2)(PPh3)2(N-N)][OTf] (N-N = 2,2′-bipyridyl (bpy) 1a, 2,2′-bipyrimidine (bpm) 2a; OTf = trifluoromethane sulfonate (CF3SO3)) complexes are reported. The cis-H2/hydride ligands are involved in H-atom site exchange between the two moieties. This dynamics was investigated by variable temperature NMR spectral studies based on which the mechanism of the exchange process was deduced. The ΔG≠ for the exchange of H-atoms between the η2-H2 and hydride ligands was determined to be around 8 and 13 kJ mol-1, respectively, for 1a and 2a. The H-H distances (dHH, A) in complexes 1a and 2a have been calculated from the T1(minimum) and 1J(H,D) and are found to be 1.07 A (slow) and 0.95 A for 1a and 1.04 A (slow) and 0.94 A for 2a, respectively. The molecular structure of 1a was determined by X-ray crystallography.
