METHOD OF PREPARING 2-ALKYL-1,4-BIS(DIETHYLALUM)BUTANES Russian patent published in 2000 - IPC

Abstract RU 2146259 C1

FIELD: polymerization and oligomerization of olefin and diene hydrocarbons, and also organometallic and fine organic synthesis. SUBSTANCE: described is method of preparing new 2-alkyl-1,4-bis(diethyl-alum)butanes of formula: wherein R is H-C6H9, H-C6H13, CH2SiMe3,. Method comprises reacting diethylaluminium chloride and metallic magnesium with mixture of alpha-olefin and dichloroethane at molar ratio of (20-24): (24-28): 10: (10-14) in the presence of zirconacene dichloride catalyst. Reaction is carried out in argon atmosphere under normal conditions for 8-12 hours. Solvent is tetrahydrofuran. EFFECT: high regloselectivity of individual 2-alkyl-1,4- bis(diethylaluma) butanes of formula I. 13 ex, 1 tbl
