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

The interaction of LnCl3 · 6H2O (Ln = Pr, Nd, and Tb) with the alkoxy derivatives of aluminum (RO)nAlCl3−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 LnCl3 · 6H2O with (RO)nAlCl3−n resulted in the partial dehydration of the crystal hydrates with the formation of an alcohol (ROH) and the LnCl3 · 3H2O · 3(RO)mAl(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.
