以（Me）LAlH)2(μ-O) (2; (Me)L = HC[(CMe)N（2,4,6- me3c6h2)]2(-)）和（Me）LAl)2(μ-Te)(μ-O)(7)为原料，分别与红硒或金属碲反应合成了重含硫铝烷[(Me)LAl(SeH)]2(μ-O)(4)和（Me）LAl)2(μ-Te)(7)。以红硒和（Me）LAlH2(1)为原料，制备了氢硒化铝[(Me)LAl(SeH)]2(μ-Se)(3)。所有化合物都通过光谱方法和x射线衍射研究进行了表征。密度泛函理论计算在4和7上进行。
Syntheses of the heavy chalcogen-containing alumoxanes [(Me)LAl(SeH)]2(μ-O) (4) and ((Me)LAl)2(μ-Te)(μ-O) (7) were accomplished by the reaction of ((Me)LAlH)2(μ-O) (2; (Me)L = HC[(CMe)N(2,4,6-Me3C6H2)]2(-)) with either red selenium or metallic tellurium. The aluminum hydrogenselenide [(Me)LAl(SeH)]2(μ-Se) (3) was also prepared from the reaction of red selenium and (Me)LAlH2 (1). All compounds were characterized by spectroscopic methods and X-ray diffraction studies. Density functional theory calculations were performed on 4 and 7.
