Abstract
A series of iron(II) dichloride complexes (Fe 1 –Fe 7 ) ligated by 2-(2-benzoxazolyl)-6-[1-(arylimino)ethyl]pyridines was synthesized and characterized [aryl = 2,6-R12C6H3; R1 = Me ( 1 ), Et ( 2 ), iPr ( 3 ), Cl ( 4 ), Br ( 5 ); 2,6-Me2C6H2-4-R2, R2 = Me ( 6 ), Br ( 7 )]. The molecular structures of Fe 1 , Fe 3 , and Fe 5 were determined by the single-crystal X-ray diffraction. Complexes Fe 1 and Fe 3 both display distorted trigonal-bipyramidal geometries, whereas complex Fe 5 is a distorted square pyramid. Upon activation with modified methylaluminoxane, all iron complexes showed moderate to good activities [up to ca. 106 g(product)?×?(mol Fe)–1 h–1?bar–1] for the oligomerization and polymerization of ethylene, with high selectivity for vinyl-terminated oligomers or polyethylene waxes.
