METHOD FOR PREPARING 1,6-DIALKYL(BENZYL)-2,5-DIPHENYL-1,5-HEXADIENES Russian patent published in 2006 - IPC C07C15/12

Abstract RU 2283296 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: method involves interaction of alkyl(benzyl)allene of the general formula (R-=^.=) wherein R means n-C₅H₁₁, n-C₆H₁₃, -CH₂Ph with EtMgBr, Mg, Cp₂TiCl₂, iodobenzene and CuCl in argon atmosphere, in tetrahydrofuran (THF) medium. The total reaction time is 18-22 h. The total yield of final substances is 61-80%. Invention provides the development of the selective method for synthesis of 1,6-dialkyl(benzyl)-2,5-diphenyl-1,5-hexadienes.

EFFECT: improved method of synthesis.
