제목 Synthesis, characterization and ethylene oligomerization studies of Ni(II) complexes ligated by [1-(1-alkyl-1H-benzoimidazol-2-yl)-alkyl-methylidene]-aryl amines
초록 The design and synthesis of efficient transition metal complex catalysts that precisely control olefin coordination polymerization and oligomerization attracted considerable interest recently. In that aspect, we have designed and synthesized a new series of Ni(II) complexes based on (benzimidazolyl-alkyl-methylidene)-aryl amines ligands. The ligands were synthesized by condensation between benzoimidazolyl-alkyl-methanones and corresponding 2, 6-dialkyl substituted anilines. Variations in the electronic nature of ligands were achieved by N-alkylation of the benzimidazol ring. The complexes showed productivity in excess of 1.6 x 106 g oligomer per mol Ni-1 h-1 towards ethylene oligomerization on activation with ethylaluminum sesquichloride producing butenes as the major product (~ 90%) along with the formation of hexenes(~10%)
