organic chemistry, chemical technology. SUBSTANCE: invention describes method of combined synthesis of novel compounds 1- ethyl-2-methylene-3-alkylalumacyclopro-panes of the general formula (I) and 1-ethyl-1,1-di-(alk-1'-ene-3'- yl)-alans of the general formula: Et-Al(CH(R)CH= CH2)2 where R is C6H13, n-C8H17 characterized that alkylalkylene of the general formula R-_._ where R is given above is subjected for interaction with ethylaluminium dichloride EtAl-Cl2 and metallic magnesium in the mole ratio R-_._ : EtAl-Cl2 : Mg = 10:(10-14), respectively, in the presence of titanacene dichloride (CpTi-Cl2) as a catalyst taken in the amount 2-6 mole% with respect to alkylalkylene in medium of tetrahydrofuran in argon atmosphere at the room temperature (~20 C) under normal pressure for 6-10 h. Proposed compounds can be used as a component of catalytical systems in processes of oligomerization and polymerization of olefinic and diene hydrocarbons and in fine organic and organometallic synthesis also. EFFECT: improved method of synthesis. 1 tbl, 10 ex |
