Synthesis of titanium trichloride complexes of 1,2,3-trisubstituted cyclopentadienyls and their use in styrene polymerization

The synthesis, characterization and styrene polymerization properties of titanium trichloride compounds (5, 1,3-dimethyl-2-n-butylcyclopentadienyl; 6, 1,3-dimethyl-2-t-butylcyclopentadienyl; 13, 1,3-diphenyl-2-n-butylcyclopentadienyl; 14, 1,3-dimethyl-2-phenylcyclopentadienyl; 15, 1,2,3-triphenylcyclopentadienyl) containing 1,2,3-trisubstituted cyclopentadienyl ligands are reported. Reactions of lithiated cyclopentadienide with Me3SiCl followed by addition of TiCl4 gave new titanium trichloride compounds 5 and 6, respectively, in reasonable yields, and reactions of cyclopentadiene with Ti(NMe2)4 followed by Me3SiCl or Me2SiCl2 gave new titanium trichloride compounds 13-15, respectively, in reasonable yields. Compound 14 has been characterized by single crystal X-ray diffraction studies: monoclinic space group P21/c; a=15.893(2), b=7.199(1), c=12.812(2) ?, β=108.394(7)°, Z=4 and V=1390.9(3) ?3. The catalytic behavior of the new titanium compounds in styrene polymerization has been studied in the presence of excess methylaluminoxane.
