METHOD FOR PREPARING 1-ETHYL-1-ALUMINA-2-OXA-3-PHENYL[(FURAN-2'-YL)]-4- ALKYLIDENECYCLOHEPTANS Russian patent published in 2004 - IPC

Abstract RU 2220972 C2

FIELD: metalloorganic chemistry, chemical technology. SUBSTANCE: invention relates to method for preparing new organoaluminum compound that can be used in fine organic synthesis and as co-catalyst in oligo- and polymerization of olefins and coupled dienes. Invention describes method for preparing 1-ethyl-1-alumina-2- oxa-3-phenyl- [(furan-2'-yl)]-4-alkylidenecycloheptan by interaction of terminal allene of the formula: R¹- CH=C=CH₂ wherein R¹ is n-C₆H₁₃, n-C₈H₁₇ with triethylaluminium of the formula AlEt₃ in the presence of zirconacene dichloride of the formula (Cp₂ZrCl₂) as a catalyst in argon atmosphere, at room temperature, under atmosphere pressure, in methylene chloride medium followed by addition at temperature 15 C cuprous chloride (CuCl) as a catalyst and aldehyde of the formula RCHO wherein R means Ch, furan-2-yl, at room temperature (~ 20 C). Invention provides preparing new compound showing high regioselectivity. EFFECT: improved preparing method. 1 tbl, 9 ex
