FIELD: chemistry of metalloorganic compounds, chemical technology.
SUBSTANCE: invention relates to a new method for preparing new magnesium-organic compounds of the general formula (1) 
wherein R means (CH2)4, (CH2)5, (CH2)6; n = 3, 4, 5. Method is carried out by interaction of α,ω-diallenes with ethyl magnesium bromide and magnesium powder in the presence of titanocene dichloride as a catalyst in argon atmosphere in tetrahydrofurane medium. Reaction time is 8-12 h. The total yield of end substances is 77-98%. Proposed compounds can be used as components of catalytic system in processes for oligo- and polymerization of unsaturated compounds and in fine organic and organometallic synthesis also.
EFFECT: improved preparing method.
