Late transition metal complexes bearing 2,9-bis(imino)-1,10-phenanthrolinyl ligands: synthesis, characterization and their ethylene activity
摘要:
A series of iron, cobalt and nickel halide complexes, LMX2 (M = Fe, X = Cl; M = Co, X = Cl, M = N-1, X = Br) bearing 2,9-bis(imino)-1,10-phenanthrolinyl ligands [L = 2,9-(ArNCH)(2)C12H6N2] were synthesized. The solid-state structures of 4 and 7 have been determined by single-crystal X-ray diffraction study. Treatment of the complexes LMX2 with methylaluminoxane (MAO) leaded to activate ethylene as oligomerization catalysts. (C) 2002 Elsevier Science B.V. All rights reserved.
