β-二亚胺配体支持的铝氧硼六元环化合物的合成、表征及其热稳定性研究

摘要

The reaction of LAlH2 (L=(Z)-4-[(2,6-diisopropylphenyl)amino]pent-3-en-2-ylidene-2,6-diisopropylaniline) with 2-trifluoromethylphenylboronic acid resulted in the boroxine-linked organic aluminum compound LAl [OB (2-CF3C6H4)]2(μ-O).Compound is an unique example of a spiro-centered aluminum atom,showing the inorganic AlO3B2 ring fused to the organic C3N2 part.Compound was characterized by 1H NMR,IR,elemental analysis,and single crystal X-ray structural analysis.Furthermore,compound was studied by TG analysis.CCDC:918118.%LAlH2(L=(Z)4-[(2,6-二异丙基苯基)氨基]戊-3-烯-2-亚基-2,6-二异丙基苯胺)与2-三氟甲基苯硼酸反应,合成含铝氧硼六元环的化合物LAI[OB(2-CF3C6H4)]2(μ-O).化合物是以铝原子为螺中心将无机环AlO3B2和有机环C3N2连在一起的独特例子.通过X射线单晶衍射测定了化合物的单晶结构,对其进行了元素分析、IR、1H NMR等表征.并通过热重分析对化合物进行了热稳定性研究.
