FIELD: chemistry. ^ SUBSTANCE: present invention pertains to the method of producing 4,5,6,7-tetra-alkyl-1,4,6,9-decatetraenes with general formula (1): where R=n-C2H5, n-C3H7, n-C5H11. The method is characterised by that, disubstituted acetylene with general formula R-=-R,where R=C2H5, n-C3H7, n-C5H11, is reacted with n-BuMgCl in the presence of zircon acene dichloride, Cp2ZrCl2, catalyst in molar ratio R-=-R: n-BuMgCl:Cp2ZrCl2=10:(22-26):(1.0-1.4) in an argon atmosphere at normal pressure, in diethyl ether for 3 hours. Allyl chloride is subsequently added at 0°C in quantity of 1.1 molar equivalents of BuMgCl and as well as CuCl in quantity of 0.1 molar equivalent of acetylene, with subsequent stirring of the reaction mixture at room temperature for 3-5 hours. ^ EFFECT: obtained substituted 4,5,6,7-tetra-alkyl-1,4,6,9-decatetraenes can be used in thin organic and metallo-ogranic synthesis as initial intermediate products when making complexes based on transition metals, substituted thiophenes, furans, cyclopentadienes and pyridines, as well as in synthesis of biologically active substances. ^ 1 tbl, 9 ex |
