Abstract RU 2130024 C1

FIELD: chemical industry, more particularly fine organic, industrial and organometal synthesis. SUBSTANCE: present invention describes method of preparing new organoaluminium compounds of formula (1): and (2): . Method comprises reacting disubstituted acetylenes of formula: R-≡-R wherein R is p-Pr, p-Bu or Ph with alkoxyaluminium dichlorides of formula: RO′-AlCl2, wherein R′ is Et,n-Bu,CH2Ph and metallic magnesium in the presence of zirconacene dichloride catalyst in amount of 2-6 mole % with respect to disubstituted acetylene. Reaction is carried out argon atmosphere under normal condition. Solvent is diethyl ether and benzene. Reaction time is 16-24 hours. Yield of desired products is 48-70%. EFFECT: more efficient preparation method. 2 cl, 13 ex, 1 tbl
