Abstract
The reaction of LAlMe2 (1) [L = HC(CMeNAr)(2), Ar = 2, 6-iPr(2)C(6)H(3)] with diphenylstannanediol resulted in the methylalumoxane compound L(Me)Al(-O)Al(Me)L (3). Compound (LAlO)(2)B(2, 6-OCH3C6H4)(-O) (4) containing the Al2BO3 six-membered ring was accomplished by reacting the precursor LAlH2 (2) with 2, 6-dimethoxyphenylboronic acid. The two compounds were characterized by H-1 NMR spectroscopy, elemental analysis, and single-crystal X-ray structural analysis.
