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

Abstract RU 2160268 C2

FIELD: chemical industry. SUBSTANCE: method comprises reacting alkoxyaluminium dichloride of formula: R′OAlCl2 wherein R′ = C2H5, C4H9 and metallic magnesium with mixture of 1,2- dialkyl(phenyl)acetylene of formula wherein R = 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 used as catalyst complex components in polymerization and oligomerization of olefin and diene hydrocarbons and also in fine, industrial and organometallic synthesis. EFFECT: more efficient combined preparation method. 15 ex, 1 tbl
