FIELD: chemistry of organoaluminum compounds, chemical technology.
SUBSTANCE: invention relates to a method for synthesis of compounds of the general formula (1): 
wherein R means ethyl (Et), n-propyl (n-Pr), n-butyl (n-Bu). Method involves interaction of disubstituted acetylenes with aluminum trichloride in the presence of metallic Mg (powder) and catalyst (Cp2ZnCl2) in argon atmosphere under atmosphere pressure and at room temperature for 8 h followed by addition of N-methylmaleinimide and stirring the reaction mass for 6-8 h at room temperature. The yield of the end substance is 76-85%. Synthesized compounds can be used in fine organic and metalloorganic synthesis and as co=catalysts in processes of oligomerization and polymerization of olefins and couples dienes.
EFFECT: improved method of synthesis.
