摘要

The boroxine-linked organic aluminum compound LAl[OB(3-C4H3O)]2(μ-O) was accomplished by reacting LAlH2 {L = (Z)-4-[(2,6-diisopropylphenyl)amino]pent-3-en-2-ylidene- 2,6-diisopropylaniline} with furan-3-ylboronic acid in good yield. The title compound belongs to the orthorhombic system, space group Pnma with a = 10.9774(15), b = 19.369(3), c = 17.362(3) Å, V = 3691.5(9) Å3, C37H47AlB2N2O5, Mr = 648.37, Z = 4, Dc = 1.167 Mg/m3, μ(MoKα) = 0.097 mm–1, F(000) = 1384, S = 1.000, the final R = 0.0589 and wR = 0.1445 for 9138 observed reflections (I > 2σ(I)) and R = 0.0683 and wR = 0.1517 for all data. This compound is an unique example of a spiro-centered aluminum atom, showing the inorganic AlO3B2 ring fused to the organic C3N2 part. It was characterized by 1H NMR, IR, elemental analysis, and single-crystal X-ray structural analysis. Furthermore, the compound was studied by TG analysis as well as DSC.
