METHOD OF OBTAINING OF 1-(DIALKYLAMINE)-3-ALKYLALUMACYCLOPENTANES Russian patent published in 1999 - IPC

Abstract RU 2139876 C1

FIELD: chemical industry, more particularly preparation of 1-(dialkylamine)-3-alkylalumacyclopentanes of formula I: C2H5, n-C4H9 wherein R is R1, n-C4H9 is n-C6H13, CH2Si(CH3)3,, as components of catalyst complexes in processes of polymerization and oligomerization of olefin and diene hydrocarbons and also in organometallic and fine organic synthesis. SUBSTANCE: method comprises reacting dialkyl amine aluminium dichloride and metallic magnesium with mixture of alpha- olefin-and dichloroethane in the presence of zirconium tetrachloride catalyst. Reaction is carried out in tetrahydrofuran in argon atmosphere under normal conditions for 8-12 hours. Method makes it possible to prepare 1-dialkyl-amine-3-alkylalumacyclopentanes of formula I with high regioselectivity. EFFECT: more efficient preparation method. 14 ex, 1 tbl
