The products formed in the reaction of MeAlCl2 with alcohols (1:1)

The products formed in the reaction (1:1) of MeAlCl2 with alcohols ROH, where R=Et, iPr, nBu, iBu, sBu, tBu, tBuCH2 were investigated. Depends on the alcohol used the formation of [Cl2Al(μ-OR)2]2AlCl or/and [Cl2Al(μ-OR)2]3Al except dimeric or/and trimeric ROAlCl2 were found. The products have been characterized by NMR and cryoscopically in benzene. The crystal structures of [Cl2Al(μ-OnBu)2]3Al and [Cl2Al(μ-OCH2tBu)]2 were determined by X-ray diffraction studies.
