A novel and improved room temperature synthesis of the monohydride catalyst trans-[RuCl(H)(dppe)(2)] complex (1, dppe (1,2-bis(diphenylphosphino)ethane) = Ph2PCH2CH2PPh2) proceeds through oxidation of methanol (the solvent) by the pentacoordinated cis-[RuCl(dppe)(2)][PF6] complex and t-BuOK as the base is described. Compound 1 was fully characterized by NMR (H-1, C-13, P-31), ESI-MS(TOF +), FTIR and elemental analysis. The X-ray structure of 1 was reported for the first time and unambiguously confirms the trans-configuration of the complex.
