METHOD OF SYNTHESIS OF 1,4-BIS [N,N-DIALKYLAMINE) ALUMINO] -TRANS-2,3-DIALKYLBUTANES Russian patent published in 1995 - IPC

Abstract RU 2039751 C1

FIELD: organometallic chemistry. SUBSTANCE: product: 1,4-bis-[(N,N-diethylamino)alumino] -trans-2,3-dibutane. Reagent 1: C6-C8-olefin. Reagent 2: [(N,N-dialkylamino)aluminium chloride] (R2N)2AlCl where R2N diethylamine or pyridine. Reagent 3: metallic magnesium. Reaction conditions: molar ratio of reagents 1, 2 and 3 is (20-22):(20-22):1. Process is carried out in the presence of catalyst containing cyclopentadienylzirconium chloride and diisobutylaluminium chloride taken at the molar ratio 1:(2-4), in argon atmosphere, at the room temperature in the medium of tetrahydrofuran for 8-12 h. EFFECT: improved method of synthesis. 1 tbl
