  Pressure Modulates Stereoregularities in the Polymerization of Propylene Promoted by rac-Octahedral Heteroallylic Complexes

  摘要：

  This communication reports the synthesis and activity of four racemic mixtures of bis(benzamidinate) group-4 complexes, cis-[p-R'C6H4C(NR)(2)](2)MX2 (R' = CH3, R = SiMe3, M = Ti, X = Cl (I); R' = CH3, R = SiMe3, M = Zr, X = Cl (2); R' = H, R = i-pr, M = Zr, X = Cl (3); R' = CH3, R = SiMe3, M = Zr, X = CH3 (4)) as precatalysts for the stereoregular polymerization of propylene. These complexes catalyze the stereoregular polymerization. of propylene only under pressure in CH2Cl2, producing polypropylene with very Large isotacticities (mmmm % = similar to 95-98), high melting points (140-154 degrees C).

  A series of Ti and Zr metallocene analogues containing bulky benzamidinate ligands has been prepared and fully characterized, Treatment of TiCl4(THF)(2) or ZrCl4(THF)(2) with two equivalents of the appropriate benzamidinate anions affords the bis(benzamidinato) complexes [C6H5C(NC3H7)(2)](2)MCl2 (M = Ti (1), Zr (2)) and [C6H5C(NC6H11)(2)](2)MCl2 (M = Ti (3), Zr (4)). Tne zirconium complex 2 was structurally characterized by X-ray diffraction. In a similar manner the nonafluoromesityl derivative [(CF3)(3)C6H2C(NC6H11)(2)](2)ZrCl2 (5) was synthesized from ZrCl4(THF)(2) and Li[(CF3)(3)C6H2C(NC6H11)(2)]. Methylation of 4 with methyllithium yields the dimethyl complex [C6H5C(NC6H11)(2)](2)ZrMe2 (6). The mixed-ligand metallocene analogues [C6H5C(NC3H7)(2)](C5Me5)MCl2 (M = Ti (7), Zr (8)) and [C6H5C(NC6H11)(2)](C5Me5)TiCl2 (9) have been prepared by reacting (C5Me5)TiCl3 or (C5Me5)ZrCl3 with one equivalent of a lithium N, N "-dialkylbenzamidinate. The polymerization of ethylene and propylene has been studied by the catalytic precatalyst complexes 1 and 2 upon reaction of an excess of methylalumoxane to obtain the active cationic complexes. The polymerization activity of the complexes is comparable to other benzamidinate ancillary containing ligands although toward shorter amounts of time due to a competitive inhibition presumably obtained by a P-hydrogen elimination from the ligand. Polymerization activity is strongly dependent on catalyst and cocatalyst concentrations and on temperature. (C) 1998 Elsevier Science B.V.
