FIELD: chemistry of metalloorganic compounds, chemical technology.
SUBSTANCE: invention relates to a method for preparing aluminum-organic compounds of the general formula (I) 
wherein R means ethyl (Et), n-propyl (n-Pr), n-butyl (n-Bu). Method involves interaction of di-substituted acetylenes with ethylaluminum dichloride (EtAlCl2) in the presence of metallic Mg and a catalyst in argon atmosphere under atmosphere pressure and room temperature for 8 h followed by addition of maleic anhydride at temperature -5°C and stirring the reaction mass at room temperature for 8 h. The yield of the end product is 56-78%. Proposed compounds can be used in fine organic and metalloorganic synthesis and as co-catalysts in processes of oligo- and polymerization of olefins and coupled dienes.
EFFECT: improved preparing method.
