  Preparation and structures of 6- and 7-coordinate salen-type zirconium complexes and their catalytic properties for oligomerization of ethylene

  摘要：

  A series of salen-type zirconium complexes of the general formula LZrCl2 (L = N,N '-ethylenebis(salicylideneiminate), 3a; N,N '-ethylenebis(3,5-di-tert -butylsalicylideneiminate), 3b; N,N '-ethylenebis(5-methoxysalicylidenciminate), 3e; N,N '-o-phethylenebis(5-chlorosalicylideneiminate), 3d; N,N '-ethylenebis(5-nitrosalicylideneiminate), 3e; N,N '-o-phenylenebis(salicylideneiminate), 4a; N,N '-o-phenylenebis(3,5-di-tert-butylsalicylideneiminate), 4b; N,N '-o-phenylenebis(5-methoxysalicylideneiminate), 4c; N,N '-o-phenylenebis(5-chloro-salicylideneiminate), 4d) were prepared. The crystal structures of 6- and 7-coordinate zirconium complexes 4b and [4b center dot OCMe2] were determined by X-ray crystallography, which reveals that a salen-type zirconium complex possesses a labile coordination site on the Zr center with a relatively stable framework and that the coordination and the dissociation of O-donor molecules occur readily at this site. The catalytic properties of 3(a-e) and 4(a-d) were studied for ethylene oligomerization in combination with Et2AlCl as co-catalyst. Complex 3c featuring a methoxy-substituted salen ligand displayed higher activity than its analogous precursors having chloro and nitro groups as substituents. The catalytic reactions by 3(a-e) and 4(a-d) gave C-4-C-10 olefins and low-carbon linear (alpha-olefins in good selectivity. (c) 2005 Elsevier B.V. All rights reserved.
