METHOD OF SYNTHESIS OF 1,4-BIS[(DIALKOXY)ALUMA]-TRANS-2,3-DIALKYLBUTANES Russian patent published in 1995 - IPC

Abstract RU 2048470 C1

FIELD: organoaluminium compounds. SUBSTANCE: product: new organoaluminium compound 1,4-bis[(dialkoxy)aluma]-trans-2,3-dialkylbutanes of the formula where R R=C2H5 or C4H9; R′=C3H7, C4H9 or C5H11. 1,4-Bis-[(dialkoxy)aluma] -trans-2,3-dialkylbutanes were synthesized by interaction of α-olefins (1-hexene, 1-heptene, 1-octene) with dialkoxyaluminium chloride of the formula (RO)2AlCl where R R=(C2H5-C4H9) and metallic magnesium at the molar ratio (20-22):(20-22):10 in the presence of (C5H5)2ZrCl2 at concentration 2-6 mole% in argon atmosphere, at the room temperature, under normal pressure in tetrahydrofuran, at stirring for 8-12 hr. The yield is 66-84% Synthesized compounds can be used in the processes of polymerization and oligomerization of olefin and diene hydrocarbons. EFFECT: improved method of synthesis, increased yield. 1 tbl
