METHOD OF PREPARING 1-ALKOXY-3-ALKYLALUMACYCLPENTANES Russian patent published in 1999 - IPC

Abstract RU 2139877 C1

FIELD: chemical industry, more particularly organometal and fine organic synthesis. SUBSTANCE: new 1-alkoxy-3- alkylalumacyclopentanes of formula I: R1 wherein CH3, C2H5, n-C4H9 is n-C4H9, n-C6H13 or CH2Si(CH3)3,, R is are useful as catalyst complex components in processes of polymerization and oligomerization of olefin and diene hydrocarbons. Alkoxyaluminium dichloride and metallic magnesium react with mixture of alpha-olefin and dichloroethane in tetrahydrofuran in the presence of zirconium tetrachloride as catalyst. Reaction is carried out in argon atmosphere under normal conditions for 8-12 hours. Yield of the desired products is 65-84%. Method makes it possible to prepare 1-alkoxy- 3-alkylalumacyclopentanes having high regioselectivity. EFFECT: more efficient preparation method. 15 ex, 1 tbl
