Description The reactions of dichloroethylalane with selected alcohols and phenols afforded a series of six new crystalline aliminum(III) chloride-alkoxides which were structurally characterized by the single crystal X-ray diffraction analysis. The prepared molecules display, depending on the steric properties of employed substituents and the reaction and crystallization conditions, a large structural variability. These compounds are by virtue of their composition suitable single-source precursors for alumina. Therefore the transformations of aluminum(III) chloride-alkoxides to aluminum(III) oxide was performed by solution thermolysis in a high-boiling solvent. The reactions are based on alkylhalide elimination which was proved by indentifying byproducts by gas chromatography-mass spectrometry.
