DERIVATIVE OF ALUMINIUM OF FORMULA Al(CF) AND METHOD OF ITS SYNTHESIS Russian patent published in 2000 - IPC

FIELD: chemistry of metalloorganic compounds. SUBSTANCE: invention proposes the metalloorganic derivative of aluminium of the formula Al(C₆F₅)₃. The above indicated derivative is synthesized by exchange reaction between the compound of the formula Al(H)_nR_m and boron metalloorganic derivative of the formula B(C₆F₅)₃ where R is taken among aliphatic, cycloaliphatic, benzylic normal or branched, monofunctional radicals containing from 1 to 20 carbon atoms; m + n = 3; n = 0 or 1 at ratio of reagents = 1:1 in hydrocarbon solvent and at reaction temperature 0-30 C. Aluminium derivative of the formula Al(C₆F₅)₃ can be used for producing catalytic systems of Zigler-Nutt type used for stereoregular polymerization of unsaturated olefinic or diolefinic monomers. EFFECT: improved method of synthesis. 8 cl, 3 dwg, 6 ex
