FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention describes a method for synthesis of 3,4-dialkyl-2,5-bis-(trimethylsilyl)-magnesa-cyclopenta-2,4-dienes of the general formula (1): 
, wherein R means n-C3H7, n-C4H9, n-C6H13. Method involves interaction of disubstituted acetylene of the general formula: R-C≡C-Si-Me3 wherein R means n-C3H7, n-C3H9, n-C6H13 with n-Bu-MgCl in the presence of zirconacene dichloride (Cp2ZrCl2) as a catalyst taken in the mole ratio R-C≡C-Si-Me3 : n-Bu-MgCl : Cp2ZrCl2 = 10:(22-26):(1.0-1.4), respectively, in argon atmosphere under normal pressure in diethyl ether medium for 10-14 h. Synthesized magnesium-organic compounds can be used as components of catalytic systems in processes of oligomerization and polymerization reactions of olefins and diene hydrocarbons, in fine, industrial organic and organometallic synthesis, and in synthesis of biologically active preparations.
EFFECT: improved method of synthesis.
