    Abstract: Compounds of formula Al.R(OR1)X where R represents C1-C3 alkyl, OR1 an alkoxy or aryloxy radical with up to 20 carbon atoms and X is chlorine, bromine or iodine are prepared by reacting an aluminium sesquihalide with an aluminium alcoholate or phenolate in stoichiometric proportions. Alcoholates and phenolates specified include those of methanol, ethanol, propanol, butanol, hexanol, octanol, dodecyl alcohol, cetyl alcohol, phenol, cresol and naphthol. The reaction is preferably carried out in an inert solvent, e.g. a halogenated hydrocarbon (carbon tetrachloride) or an aromatic hydrocarbon (benzene, toluene or xylene), and in the absence of air and moisture. The products may be used as reducing agents and polymerisation catalysts.
