Dimeric Ru(II) complexes Ru2(CO)4L2X 4 (L = CO or PPh3; X = Cl or Br) have been found to catalyze the hydrolysis of silanes to produce hydrogen gas and silanols with turnover numbers in excess of 104 at room temperature. Deuteration and mass spectrometric studies have established that the hydrogen gas originates from one hydrogen atom from water and the other from silane. Ruthenium hydride intermediates have been detected in the NMR spectrum during the early stage of the reaction, while the FTIR spectra of more stable complexes such as Ru(CO)2(PPh3)(THF)Br2 and Ru(CO) 2(PPh3)2(H)Br have been recorded upon completion of catalysis. A mechanism has been proposed to account for the ruthenium-catalyzed silane hydrolysis based on the experimental data.

Reaction of Ru(CF3)Br(CO)2(PPh3)2 with an excess of BBr3 produces a red salt identified as .Upon standing this solid loses CO and BBr3, to form , A, the structure which has been determined by X-ray diffraction.The geometry about ruthenium is approximately octahedral, with the two phosphorus atoms of the tridentate bisphosphinocarbene ligand mutually trans, a one bromide trans to the carbene carbon.The other bromide and the carbonyl ligand are statistically interchanged about a crystallographic diad axis which passes through the carbene carbon,the ruthenium, and the trans bromide.The Ru-P distance is 2.353(2) Angstroem, the Ru-Br distances are 2.638(2) Angstroem (trans to carbene) and 2.537(2) Angstroem (trans to CO), and the Ru=C(carbene)distance is 1.941(12) Angstroem.Bromide is removed from compound A by treatment with AgSbF6 in MeCN to give , and this when treated with CO gives .The dicarbonyl cation reacts with NaBH4 to give , and with HNEt2 to give .
