摘要
The reactions of LAlH2 (L = HC(CMeNAr)(2), Ar = 2,6-iPr(2)C(6)H(3)) (1) with diphenylsilanediol, phenylphosphonic acid, diphenylphosphinic acid, and pyrocatechol afford compounds with the Al-O-X (X = Si, P, C) motif of composition [LAl(mu-O)](2)Si(Ph)(2) (2), [LAl(mu-O)](2)PO(Ph) (3), LAl[OPO(Ph)(2)](2) (4), and LAl(mu-O)(2)(o-C6H4) (5), respectively. Compound 2 contains the Al-O-Si-O-Al heterotrimetallic dioxide chain. Compound 3 features an Al(mu-O)](2)P four-membered ring, while compound 4 exhibits a P-O-Al-O-P chain structure. Compound 5 contains the benzo-aluminum-dioxide organic-inorganic hybrid five-membered ring. Complexes 2, 3, 4, and 5 were characterized by NMR, elementary analysis, and single-crystal X-ray diffraction.
