METHOD OF COMBINED SYNTHESIS OF 1,2-BIS-(DIETHYL-ALUMA)-1- METHYLENE-2-ALKYLETHANES AND 1,4-BIS-(DIETHYLALUMA)-1,4- DIALKYLIDENEBUTANES Russian patent published in 2003 - IPC

Abstract RU 2197496 C2

FIELD: organic chemistry, chemical technology, catalysts. SUBSTANCE: invention describes method of combined synthesis of 1,2-bi-(diethyl-aluma)- 1-methylene-2-alkylethanes of the formula (1) and 1,4-bis-(diethylaluma)-1,4- dialkylidenebutanes of the formula (2) where R means n-C6H13, n-C8H17, n-C9H19 characterized that alkylallenes of the general formula where R as given above are subjected for interaction with diethylaluminium chloride of the formula Et2AlCl and metallic magnesium taken in the mole ratio : Et2AlCl : Mg = 10:(20-25):(10-14), respectively, in the presence of titanacene dichloride as catalyst taken in the amount 2-6 mole % with respect to alkylallene in tetrahydrofuran (THF) medium, at the room temperature and under normal pressure for 8-12 h. New compounds can be used as component of catalytic systems in processes of oligomerization and polymerization of olefin and diene hydrocarbons and in fine organic and organometallic synthesis. EFFECT: improved method of synthesis, valuable properties of compounds. 1 tbl
