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

A series of 2,6-bis(imino)pyridyl iron(III) complexes of the general formula [2,6-(ArNCMe)2C5H3N]FeCl3 (Ar = -C6H5, 3a; 2-MeC6H4, 3b; 2-EtC6H4, 3c; 2-iPrC6H4, 3d; cyclohexyl, 3e; 4-MeC6H4, 3f; 4-iPrC 6H4, 3g; 4-FC6H4, 3h and 4-CF 3C6H4, 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.

Bis(arylimino)pyridine iron(III) complexes as catalyst precursors for the oligomerization and polymerization of ethylene

A series of 26 bis(arylimino)pyridine iron(III) complexes containing either electron withdrawing or electron donating substituents in their ligand frameworks was synthesized and characterized. After activation with methylaluminoxane (MAO), these catalysts

A new approach to symmetric 2,2':6',2'-terpyridines

A novel four step process for the preparation of symmetric terpyridines is presented. The title compound, 2,2':6',2'-terpyridine (1a) and a substituted derivative, 5,5'-dimethyl-2,2':6',2'-terpyridine (1b) are prepared. Both 1a and 1b share a common precursor, 2,6-diacetylpyridine (2) and are prepared in overall yields of 73 and 93% respectively. The purities of the crude terpyridine products are in the 90-95% range.
