Cyclopentadienyl-Ruthenium and -Osmium Chemistry. XXXI. Preparation of Some Complexes Containing 1,1'-Bis(diphenylphosphino)ferrocene (dppf): X-Ray Structure of RuH(dppf)(η-C5H5)

Abstract

Exchange of 2PPh3 for Fe(η-C5H4PPh2)2 ( dppf ) in RuCl (PPh3)2(η-C5H5) (80°C, 16 h) afforded RuCl ( dppf )(η-C5H5), which was converted into the corresponding hydride and 1,2-bis( methoxycarbonyl )vinyl derivatives. Crystals of RuH ( dppf )(η-C5H5) are triclinic, space group Pī with a 14.392(3), b 20.175(5), c 12.379(2)Ǻ, α 105.02(2),β 109.73(2),γ 96.56(2)° and Z 4. The structure was refined by a blocked-matrix least-squares procedure to R 0.055 and Rw 0.056 for 3917 reflections with I ≥ 2.5σ(I).
