METHOD OF COMBINED PREPARATION OF 1-(DIALKYLAMINE)-2,3- DIALKYL(PHENYL)ALUMACYCLOPROPENES, 1-(DIALKYLAMINE)-2,3- DIALKYL(PHENYL)ALUMACYCLOPENT-2-ENES AND 1- (DIALKYLAMINE)-2,3,4,5-TETRAALKYLALUMACYCLOPENTADIENES Russian patent published in 2000 - IPC

FIELD: fine, industrial and organometallic synthesis. SUBSTANCE: method comprises reacting dialkylaluminium dichloride of formula R′NAlCl₂ wherein R′ is C₂H₅, C₃H₇ and metallic magnesium with mixture of 1,2-dialkyl(phenyl)acetylene of formula R-≡-R wherein R is C₃H₇, C₄H₉, Ph and dichloroethane at molar ratio of (10-14):(22-30):10:(10-14), respectively, in the presence of titanocene dichloride catalyst in amount of 2-6 mole % with respect to disubstituted acetylene in argon atmosphere under normal conditions for 8-12 hours. The resulting new compounds are useful as catalyst complex components in processes of polymerization and oligomerization of olefin and diene hydrocarbons. EFFECT: more efficient preparation method. 15 ex, 1 tbl
