摘要
Towards new polymerization-catalyst activators: A new synthetic approach is described for the hitherto unknown [{LAI(OH)}2(μ-O)]·0. 5 (C7H8)·C6H14 species (1; L = HC[(CMe)(2,6-iPr2C6H3N)]2). Further reaction of the Brönsted acidic OH groups of 1 with Me 2AlH results in the formation of trimeric alumoxane containing a three coordinate Al center [(LAI)2-(MeAl)(μ-O) 3]·2 C7H8, the core of which is depicted. These compounds may have use as activators for olefin-polymerization catalysts.
