FIELD: chemistry of organometallic compounds, organometallic synthesis.
SUBSTANCE: invention relates to a method for synthesis of 2,3,4,5-tetralalkylmagnesa-cyclopenta-2,4-dienes. Method is carried out by interaction of disubstituted acetylenes with n-Bu-MgCl in the presence of zirconocene dichloride as a catalyst in argon atmosphere at room temperature in diethyl ether medium for 10-14 h. Invention provides simplifying the method and using the available reagents.
EFFECT: improved method of synthesis.
