  摘要：

  The synthesis of four new bidentate ligands, 2-(tetramethylcyclopentadienyl)-4,6-di-tert-butylphenol ((TCDBP)H-2, 5), 2-(tetramethylcyclopentadienyl)-6-tert-butylphenol ((TCBP)H2, 6), 2-(tetramethylcyclopentadienyl)-6-phenylphenol ((TCPP)H-2, 7), and 2-(tetramethylcyclopentadienyl)-6-methylphenol ((TCMP)H-2, 8), as well as their corresponding constrained geometry tetramethylcyclopentadienyl-phenoxytitanium dichlorides (TCDBP)TiCl2 (9), (TCBP)TiCl2 (10), (TCPP)TiCl2 (11), and (TCMP)TiCl2 (12) are described. A new method for the synthesis of complexes 9-12 was developed. Molecular structures of 9, 10, and 11 were determined by single-crystal X-ray diffraction. The Cp(cent)-Ti-O angles of 106.8degrees for 9, 107.1degrees for 10, and 107.3degrees for 11 reveal their sterically open features as catalyst precursors. When activated with (Bu3Al)-Bu-i and Ph3C+B(C6F5)(4)(-), complexes 9-12 exhibit reasonable catalytic activity for ethylene polymerization, producing polyethylenes with moderate molecular weights and melting points.

  日期：2006.1.1

  This report describes a highly efficient one-step synthetic strategy for monocyclopentadienyltitanium complexes by the direct reaction of TiCl4 with substituted cyclopentadienes, without adding any other reagents. This new synthetic method is particularly efficient for cyclopentadienes with a pendant group that can bond or coordinate to the Ti atom.

  该报告描述了单环戊二烯基钛配合物的高效一步合成策略，该方法通过使TiCl 4与取代的环戊二烯直接反应而无需添加任何其他试剂。对于具有可与Ti原子键合或配位的侧基的环戊二烯，这种新的合成方法特别有效。
