Figure 00000001

где R представляет н-C4H9, н-C6H13, CH2SiMe3,
отличающийся тем, что к реакционной массе, состоящей из диэтилалюминийхлорида (Et2AlCl) и металлического магния добавляют в течение 6 часов в среде тетрагидрофурана смесь, содержащую α- олефин общей формулы
Figure 00000002
где R представляет н-C4H9, н-C6H13, CH2SiMe3, и дихлорэтан в мольном соотношении (20oC24):(24oC28):10:(10oC14), и реакцию осуществляют в присутствии катализатора цирконацендихлорида, взятого в количестве 3-8 мол.% по отношению к олефину, в атмосфере аргона, при комнатной температуре в течение 8-12 час.The method of producing 2-alkyl-1,4-bis (diethyl aluminum) butanes of the general formula
Figure 00000001

where R is nC 4 H 9 , nC 6 H 13 , CH 2 SiMe 3 ,
characterized in that a mixture containing α-olefin of general formula is added to a reaction mass consisting of diethyl aluminum chloride (Et 2 AlCl) and magnesium metal for 6 hours
Figure 00000002
where R is n-C 4 H 9 , n-C 6 H 13 , CH 2 SiMe 3 , and dichloroethane in a molar ratio (20 o C24) :( 24 o C28): 10: (10 o C14), and the reaction is carried out in the presence of a catalyst of zirconacene chloride, taken in an amount of 3-8 mol.% relative to the olefin, in an argon atmosphere, at room temperature for 8-12 hours
