摘要：

The title compound (1) can be converted into H2Ru4CO)11(mu4-eta2-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(mu4-N2Et2)(mu-CPh=CH2) (3) or Ru4(CO11(mu4-N2Et2)(mu4-HC=CPh) (4).
