  Highly trans-1,4 selective polymerization of 1,3-butadiene initiated by iron(III) bis(imino)pyridyl complexes

  摘要：

  A series of 2,6-bis(imino) pyridyl iron(III) complexes of the general formula [2,6-(ArN=CMe)(2)C5H3N] FeCl3 (Ar = -C6H5, 3a; 2-MeC6H4, 3b; 2-EtC6H4, 3c; 2-(PrC6H4)-Pr-i, 3d; cyclohexyl, 3e; 4-MeC6H4, 3f; 4-(PrC6H4)-Pr-i, 3g; 4-FC6H4, 3h and 4-CF3C6H4, 3i), activated by alkylaluminum, MAO or MMAO, have been investigated in 1,3-butadiene polymerization. Iron(III) complex (3a), with the least steric hindrance around the metal center, gives polymer up to 99% in yield in 4 h (butadiene to iron ratio = 1000), and trans-1,4 selectivity about 94.7% at room temperature in toluene, while those (3b-3d) bearing alkyl substituents at the 2-position of each N-aryl ring exhibit much lower catalytic activity and tunable trans-1,4 selectivity. Introduction of an alkyl group at the 4-position (para-position, 3f and 3g) exerts a slightly beneficial effect on the trans-1,4 selectivity, while electronegative groups at the same position (3h and 3i) affect negatively on the activity. The effects of temperature, types of cocatalyst and Al/Fe molar ratio on the polymerization behavior are investigated. More importantly, a mechanism for forming trans-1,4 structure is also proposed.

  4-trichlorobenzene, fluorobenzene, 2-, 3-, and 4-chlorobiphenyl, and 4,4′- and 3,5-dichlorobiphenyl and the hydrogenation of benzene, toluene, p-xylene, styrene, α-methylstyrene, biphenyl, aniline, phenol, and pyridine. A Hg(0) poisoning test reveals that homogeneous and heterogeneous catalysis coexist during the dehalogenation reactions, whereas the hydrogenation processes are heterogeneous. The nanoparticles

• New iron-based bis(imino)pyridine and acetyliminopyridine complexes as single-site catalysts for the oligomerization of ethylene

  日期：2004.4

  New iron-based bis(imino)pyridine complexes 6, 7 and the acetyliminopyridine complex 8a are active catalysts together with the co-catalyst MAO for the oligomerization of ethylene. The ligands 1-4 with electron donating methoxy- and electron withdrawing trifluoromethyl-substituents react with FeCl2 (thf)(2) to the Fe(II) complexes 6-8a. Especially p-methoxy substituents in 6b increase the selectivity in the production of alpha-olefins. The distribution of oligomers obtained in the catalyzed ethylene oligomerization with 5-8a follows Schulz-Flory rules for oligomers >C-4. The probability of chain propagation ot is increased by lowering the reaction temperature, while higher pressure of the ethylene gas in the reaction has nearly no effect on the ce-values.
