  Alkyne-functionalized metallocene complexes: Synthesis, structure, and catalytic ethylene polymerization

  摘要：

  Reactions of phenylethynyl lithium with substituted cyclopentenones gave the corresponding pendant phenylethynyl substituted cyclopentadienes. Subsequent deprotonation and transmetallation with TiCl4 center dot 2THF, ZrCl4, and Cp*ZrCl3 yielded the alkyne-functionalized metallocene complexes [C5Me4(C=CPh)](2)MCl2 [M = Ti (1), Zr (2)], Cp*[C5Me4(C=CPh)]ZrCl2 (3), and Cp*[C5H2R'(2)(C=CPh)]ZrCl2 [R' = Me (4), Ph (5)]. These complexes were fully characterized by H-1 NMR, C-13 NMR, MS spectra, and elemental analysis. The molecular structure of 2 was determined by single crystal X-ray diffraction analysis. Ethylene polymerization was studied with these complexes in the presence of methylaluminoxane (MAO). (C) 2011 Elsevier Ltd. All rights reserved.
