Towards new polymerization‐catalyst activators : A new synthetic approach is described for the hitherto unknown [{LAl(OH)} 2 (μ‐O)]⋅0.5 (C 7 H 8 )⋅C 6 H 14 species ( 1 ; L=HC[(CMe)(2,6‐ i Pr 2 C 6 H 3 N)] 2 ). Further reaction of the Brönsted acidic OH groups of 1 with Me 2 AlH results in the formation of trimeric alumoxane containing a three coordinate Al center [(LAl) 2 (MeAl)(μ‐O) 3 ]⋅2 C 7 H 8 , the core of which is depicted. These compounds may have use as activators for olefin‐polymerization catalysts.
