Interaction of LnCl3 • 6H2O crystal hydrates with the alkoxy derivatives of aluminum in organic solvents

The interaction of LnCl(3) (.) 6H(2)O (Ln = Pr, Nd, and Th) with the alkoxy derivatives of aluminum (RO)(n)AlCl3-n (where R = Et or iso-Bu; n = 1-3) in organic solvents was studied. It was found that the reaction of the crystal water of LnCl(3) (.) 6H(2)O with (RO)(n)AlCl3-n resulted in the partial dehydration of the crystal hydrates with the formation of an alcohol (ROH) and the LnCl(3)(.)3H(2)O(.)3(RO)(m)Al(OH)Cl2-m complex (m = 1, 2). The solid colloidal particles of this complex and a solvent form a lanthanide-containing gel. The physicochemical (including luminescence) and catalytic properties of the complex in butadiene polymerization and 1,1-gem-dibromo-2-phenylcyclopropane dehalogenation were studied.
