METHOD FOR PREPARING 1,6-DIALKYL-2,5-BIS-(ETHYLMAGNESA)-1,5-HEXADIENES

摘要

FIELD: chemistry of organometallic compounds, chemical technology.;SUBSTANCE: invention relates to a method for preparing new magnesium-organic compounds that can be used as a component of catalytic systems in processes of oligomerization and polymerization of olefin, diene and acetylene hydrocarbons and in fine organic and organometallic syntheses also. The proposed method is carried out by interaction of alkylallenes with ethyl magnesium bromide and activated magnesium in the presence of titanocene dichloride as a catalyst in argon atmosphere, in tetrahydrofuran (TGF) medium. Reaction time is 8-12 h. The total yield of end products is 74-94%. Invention provides expanding assortment of new magnesium-organic compounds that can be used as catalytic components for polymerization of olefin, diene and acetylene hydrocarbons and in fine organic and organometallic syntheses also.;EFFECT: improved preparing method.;1 tbl, 11 ex
