diphenylstannanediol resulted in the methylalumoxane compound L(Me)Al(μ-O)Al(Me)L (3). Compound (LAlO)2B(2, 6-OCH3C6H4)(μ-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 1H NMR spectroscopy, elemental analysis, and single-crystal X-ray structural analysis.
LAlMe2 (1) [L = HC(CMeNAr)2, Ar = 2, 6-iPr2C6H3] 与二苯基锡二醇反应生成甲基铝氧烷化合物 L(Me)Al(μ-O)Al(Me)L (3)。通过使前体 LAlH2 (2) 与 2, 6-二甲氧基苯基硼酸反应,得到含有 Al2BO3 六元环的化合物 (LA1O)2B(2, 6-OCH3C6H4)(μ-O) (4)。通过1H NMR光谱、元素分析和单晶X射线结构分析对这两种化合物进行了表征。
