METHOD OF COMBINED PREPARATION OF 1-ETHYL-2- PHENYLALUMACYCLOPROPANE AND 1-ETHYL-2,4- DIPHENYLALUMACYCLOPENTANE Russian patent published in 2000 - IPC

Abstract RU 2153499 C2

FIELD: chemical industry. SUBSTANCE: described is method of combined preparation of 1-ethyl-2-phenylalumacyclopropane of formula I: and 1-ethyl-2,4-diphenylalumacyclopentane of formula II: . Method comprises reacting styrene () with ethyl aluminium dichloride ((EtAlCl2)) and metallic magnesium at molar ratio of 10: (10-14): (10-14) in the presence of two- component catalyst composed of zirconium tetrachloride and diisobutyl aluminium hydride at molar ratio of 1: (2- 4). Reaction is carried out in argon atmosphere, in tetrahydrofuran under normal conditions for 6-10 hours. The claimed method makes it possible to prepare new individual 1-ethyl-2,4-diphenyl-alumacyclopentane and 1- ethyl-2-phenylalumacyclopropane which are useful components of catalytic system in processes of oligomerization and polymerization of olefin and diene hydrocarbons and also in fine industrial and organometal synthesis. EFFECT: more efficient preparation method. 11 ex, 1 tbl
