Reaction of 2> (cp=η5-cyclopentadienyl) with P(OR)3 ligands (R=Me, Et, or Bun) yields , 2>, and > complexes resulting from C-O bond cleavage.The former complexes were characterized by reaction with PPh3 which yields the acyl derivative.Reaction of 2> with PPr3 and PMe2Ph proceeds to yield a mixture of the substituted dimer and the hydrides (x=0 or 1) depending on the reaction conditions.The mechanisms of these reactions and the fluxionality of the substituted dimers are discussed.

The ruthenium chloride and hydride complexes Cp(PR3)2RuH {X = Cl; PR3 = PMe3 (1), PMe2Ph (2), PMePh2 (3), PPh3 (4); X = H; PR3 = PMe3 (5), PMe2Ph (6), PMePh2 (7), PPh3 (8)} were studied by spectroscopy and solution calorimetry. The structures of 2 and 3 are reported and complete the structural characterization of the series 1-4. In this series, the Ru-Cl distance (2.449 ± 0.007 A?) remains constant, while the Ru-PR3 distance increases in the order 1 2 3 4. The ruthenium hydrides 5-8 were prepared from the reaction of the corresponding ruthenium chloride with KOMe in methanol.
