METHOD FOR PREPARING 4,7-DIALKYL(BENZYL)IDENE-2,10-DODECADIENES Russian patent published in 2006 - IPC C07C11/21

Abstract RU 2286328 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: method involves carrying out the interaction of alkyl(benzyl)allene of the general formula (R-=^.=) wherein R means n-C₅H₁₁, n-C₆H₁₃, -CH₂Ph with EtMgBr, Mg, Cp₂TiCl₂, crotyl bromide and CuCl in argon atmosphere in tetrahydrofuran medium. The total reaction time is 18-22 h and the total yield of end products is 63-81%. Invention provides the development of method for synthesis of 4,7-dialkyl(benzyl)idene-2,10-dodecadienes.

EFFECT: improved method of synthesis.
