Yttrocene Chloride and Methyl Complexes with Variously Substituted Cyclopentadienyl Ligands: Synthesis, Characterization, and Reactivity toward Ethylene

Popis výsledku v původním jazyce

The reaction of YCl3 center dot 3.5THF with 1 equiv. of Li(C5Me4SiMe3) afforded in high yield the ionic complex [Li(thf)(4)](+){[(eta(5)-C5Me4SiMe3)YCl2](4)(mu(4)-Cl)}(-) (1). The molecule of 1 consists of the tetranuclear anion {[(eta(5)-C5Me4SiMe3)YCl2](4)(mu(4)-Cl)}(-) compensated with [Li(thf)(4)](+) in the solid state. Reactions of compound 1 with selected lithium and potassium cyclopentadienides resulted in the formation of yttrocene chloride complexes [(eta(5)-C5Me4SiMe3)Y(L)(mu-Cl)(2)M(thf)(2)] [M = Li, L = eta(5)-C5H5 (2); M = Li, L = eta(5)-C5Me5 (3); M = Li, L = eta(5)-C5Me4SiMe2H (4); M = K, L = eta(5)-C5Me4CH2Ph (5)]. Yttrocene chloride complexes 2-5 underwent methylation reactions to give yttrocene methyl complexes [(eta(5)-C5Me4SiMe3)Y(L)(mu-Me)(2)Li(thf)(2)] [L = eta(5)-C5H5 (6); L = eta(5)-C5Me5 (7); L = eta(5)-C5Me4SiMe2H (8); L = eta(5)-C5Me4CH2Ph (9)]. The products of all these reactions were characterized by NMR and IR spectroscopy, and 2-5 were further studied by ESI mass spectrometry. The molecular structures of 1 and 4 were determined by single-crystal XRD. The methyl-bridged complexes 6-9 were tested as homogeneous catalysts for ethylene polymerization in the absence of cocatalysts.
