FIELD: chemistry of organometallic compounds, chemical technology.
SUBSTANCE: invention relates to metalloorganic synthesis, namely, to a method for synthesis of 1-hloro-3,4-dialkyl-2,5-bis-(trimethylsilyl)-aluminacyclopenta-2,4-dienes of the general formula (1): 
wherein R means n-C3H7, n-C4H9, n-CH13. Method involves interaction of disubstituted acetylenes with AlCl3 and metallic Mg in the presence of zirconacene dichloride as a catalyst in tetrahydrofuran (TGF) medium, in argon atmosphere, at room temperature for 14-18 h. Synthesized compounds can be used as a component of catalytic system used in processes of oligomerization and polymerization of olefins and diene hydrocarbons, in fine industrial organic and metalloorganic synthesis, and in synthesis of biologically active preparations.
EFFECT: improved method of synthesis.
