Derivative Chemistry of the Cluster Ru4(CO)12(μ4η2-N2Et2)The title compound (1) can be converted into H2Ru4CO)11(μ4-η2-N2Et2) (2) in three ways: a) by direct hydrogenation, b) by a H - /H+ sequence, c) by reduction with Na/Hg (reversible with FeCp2+/CO) and subsequent protonation. The structure of 2 has been determined by an X-ray analysis. 2 is a dibasic acid and shows ligand fluxionality as demonstrated by NMR. 2 adds phenylacetylene either by insertion into one Ru - H bond or by H2 replacement yielding HRu4(CO)10(μ4-N2Et2)(μ-CPh≡CH2) (3) or Ru4(CO11(μ4-N2Et2)(μ4-HCCPh) (4).
