FIELD: organic synthesis.
SUBSTANCE: invention relates to preparation of novel organomagnesium compounds, which consists in reaction of alkylallenes with diethylmagnesium in presence of zirconacene dichloride as catalyst used in amount 0.2 to 0.6 mmole based on alkylallene in diethyl ether medium under argon atmosphere, reaction time being 8-12 h.
EFFECT: extended assortment of organomagnesium compounds, which can find use as components of catalytic systems in processes of oligo- and polymerization of olefin, diene, and acetylene hydrocarbons as well as in delicate organic and organometallic syntheses.
