  equivalents of potassium 1,2-diphenylethenide in THF, followed by reaction with [YbI2(THF)2] at 60 °C, gave the trivalent ytterbium ate complex [K(DME)][Yb(η5:η1-C5H3tBu-3)SiMe2NtBu}2]. A single crystal X-ray diffraction study of this complex shows polymeric chains consisting of trivalent ytterbocene units with two chelating amidocyclopentadienyl ligands coordinated to potassium ions.

  sigma -Bond metathesis of the new linked amino-cyclopentadiene (C5Me4H)CH2SiMe2NHCMe3 with Y(CH2SiMe3)(3)(THF)(2) gave the alkyl-yttrium complex [y(eta (5):eta (1)-C5Me4CH2SiMe2NCMe3)(CH2SiMe3)(THF)] (1) in 66% yield. Compound 1 was characterized by NMR spectroscopy and X-ray crystal structure analysis. By hydrogenolysis, 1 was quantitatively converted into the dimeric hydride [Y(eta (5):eta (1)-C5Me4CH2SiMe2NCMe3)(THF)(mu -H)](2) (2). X-ray crystal structure analysis revealed a Y2H2 core connected to two [Y(eta (5):eta (1)-C5Me4CH2SiMe2NCMe3)(THF)] fragments in a skewed manner, with a relatively long yttrium-yttrium distance of 3.7085(8) A. In solution, two diastereomers were observed by H-1 NMR spectroscopy at -78 degreesC. Dimer 2 was shown to efficiently catalyze the hydrosilylation of 1-decene with PhSiH3 to give the terminal silane (C10H21SiH2Ph)-C-n exclusively. Although the product of addition of the yttrium-hydride complex 2 to styrene, [Y(eta (5):eta (1)-C5Me4CH2SiMe2NCMe3)CH(CH3)Ph}(THF)] (3), contains a 1-phenethyl ligand derived from internal addition, hydrosilylation of styrene with PhSiH3 catalyzed by 2 gave both terminal- and internal-hydrosilylated products in a ratio of 1:1.4.
