Abstract
AbstractTreatments of β‐diketiminate aluminum dihydride LAlH2 (L=HC[C(Me)N(Ar)]2, Ar=2,6‐iPr2C6H3) with (2‐chlorophenyl)methanol, 2,3‐dimethylbutane‐2,3‐diol, 2,2‐dimethylpropane‐1,3‐diol, 2,2‐bis(bromomethyl)propane‐1,3‐diol, and p‐diphenol resulted in the formation of compounds containing the C−O−Al−O−C linkages, including the acyclic LAl[(μ‐O)CH2(o‐Cl−C6H4)2]2 (1), the five‐membered ring LAl[(μ‐O)CMe2]2 (2), the six‐membered ring LAl[(μ‐O)CH2]2CMe2 (3) and LAl[(μ‐O)CH2]2C(CH2Br)2 (4), and the macrocyclic [LAl(μ‐O)2(p‐C6H4)]4 (5), respectively. These practices prove that β‐diketiminate aluminum dihydride is a valuable precursor for the preparation of acyclic and cyclic systems. 1–5 were characterized by melting point, 1H and 13C NMR, FT‐IR, and single‐crystal X‐ray diffraction studies.
