Popis výsledku v původním jazyce
The reaction of YCl33.5THF with 1 equiv. ofnLi(C5Me4SiMe3) afforded in high yield the ionic complexn[Li(thf )4]+{[(η5-C5Me4SiMe3)YCl2]4(μ4-Cl)}– (1). The molecule of 1nconsists of the tetranuclear anion {[(η5-C5Me4SiMe3)YCl2]4(μ4-nCl)}– compensated with [Li(thf )4]+ in the solid state. Reactionsnof compound 1 with selected lithium and potassium cyclopentadienidesnresulted in the formation of yttrocene chloride complexesn[(η5-C5Me4SiMe3)Y(L)(μ-Cl)2M(thf)2] [M = Li, L = η5-C5H5n(2); M = Li, L = η5-C5Me5 (3); M = Li, L = η5-C5Me4SiMe2H (4);nM = K, L = η5-C5Me4CH2Ph (5)]. Yttrocene chloride complexes 2–5 underwent methylation reactions to give yttrocene methylncomplexes [(η5-C5Me4SiMe3)Y(L)(μ-Me)2Li(thf )2] [L = η5-C5H5 (6);nL = η5-C5Me5 (7); L = η5-C5Me4SiMe2H (8); L = η5-C5Me4CH2Phn(9)]. The products of all these reactions were characterized bynNMR and IR spectroscopy, and 2–5 were further studied by ESInmass spectrometry. The molecular structures of 1 and 4 werendetermined by single-crystal XRD. The methyl-bridged complexesn6–9 were tested as homogeneous catalysts for ethylenenpolymerization in the absence of cocatalysts.
