摘要：

Bis(pyridine)iron dialkyl complexes FeR2Py2 (R = CH2Ph, CH2CMe2Ph, and CH2SiMe3) react with 2,6-diiminopyridine ligands, affording the corresponding organoiron complexes. The complex Fe(CH2SiMe3)(2)-(C5H3N-2,6-(C(=N-mesityl)Me)(2), 4a, becomes an active ethylene polymerization catalyst upon treatment with Al or Zn alkyls. A catalytically active 1:1 Fe/Al adduct has been detected in solution by H-1 and LTV-vis spectroscopies.
