摘要
LAl H2(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)分别与2-噻吩苯硼酸和2-苯并噻吩硼酸反应,合成含铝氧硼六元环的化合物LAl[OB(2-thiophen)]2(μ-O)(2)和LAl[OB(2-benzo[b]thiophen)]2(μ-O)(3)。LAl H2与2,6-二甲基苯硼酸反应生成了LAl[OB(2,6-CH3C6H4)OH]2(4)。化合物4是化合物2和3的中间体。所有化合物都进行了IR、1H NMR和元素分析等表征。并通过X射线单晶衍射测定了化合物2和4的单晶结构。
The reaction of LAlH2（L=（Z）-4-[（2,6-diisopropylphenyl）amino]pent-3-en-2-ylidene-2,6-diisopropylaniline）（1） with thiophen-2-ylboronic acid and benzo[b]thiophen-2-ylboronic acid resulted in the boroxine-linked aluminumcompounds LAl[OB（2-thiophen）]2（μ-O） （2） and LAl[OB（2-benzo[b]thiophen）]2（μ-O） （3）, respectively. LAl[OB（2,6- CH3C6H4）OH]2 （4） was synthesized by the reaction of 1 with 2, 6-dimethylphenylboronic acid. 4 is the intermediate analogue of the reaction to 2 and 3, which we postulated for the formation of 2 and 3. All compounds were characterized by IR, 1H NMR and elemental analysis. Furthermore, compounds 2 and 4 were characterized by singlecrystal X-ray diffraction studies. Compound 2 crystallizes in the triclinic space group P1 while 4 crystallizes in the monoclinic P21/c space group. For the structure of 2, one aluminum atom, two boron atoms, and three oxygen atoms form a six-membered planar AlB2Os ring. The central aluminum atom is located in the spirocyclic center where the inorganic AlB2Os ring is fused to the organic C3N2 part. However, comoound 4 consists of the metallic-nonmetallicchain of （H）O-B-O-Al-O-B-O（H） as a backbone. CCDC： 981567, 2; 981568, 4.
