  Synthesis and ethylene polymerization behavior of {MeB(3-Ph-pyrazolyl)3}TiCl3

  摘要：

  The new methyl-tris(pyrazolyl) borate reagents Li[MeTp(Ph)](1)[MeTp(Ph)](-) = MeB(3-Ph-pyrazolyl)(3)(-)) and Tl[MeTp(Ph)] (2) react with TiCl4 to afford (MeTp(Ph))TiCl3 (3) in 77% and 81% yield respectively. 2 reacts with ZrCl4 and HfCl4 to yield mixtures of products. The reaction of 1 with TiCl3(THF)(3) proceeds with B-N bond cleavage to afford TiCl3(3-Ph-pyrazole)(THF)(2) as the major product (30%). The reaction of 3 with MeLi (3 equiv) yields 1 (60%) and reduced Ti species, via apparent displacement of [MeTp(Ph)](-) and generation of unstable TiCl4Me4-x species. Under MAO activation conditions (MAO = methylalumoxane), 3 polymerizes ethylene to linear polyethylene. 3/MAO is significantly more active in ethylene polymerization than the hydrido-tris(pyrazolyl)borate analogue {HB(3-Ph-pyrazolyl)(3)}TiCl3/MAO.
