    摘要: This invention relates to a process for isomerizing 1,4-dichloro-2-butene to yield 3,4-dichloro-1-butene or 3,4-dichloro-1-butene to yield 1,4-dichloro-2-butene, characterized in that the catalyst used comprises a compound of the formula CpFe(CO)2X, wherein Cp denotes a cyclopentadienyl derivative of the general formula (I), wherein R1 to R5 mutually independently denote H, C1 to C12 alkyl, C5 to C8 cycloalkyl, which may in turn bear C1 to C12 alkyl groups, C6 to C14 aryl, alkylaryl, arylalkyl, wherein two adjacent residues may together form saturated or unsaturated C3 to C14 cycles, or denote—SiR6R7R8, wherein R6 to R7 may mutually independently mean C1 to C4 alkyl, C5 to C8 cycloalkyl or C6 to C14 aryl, and X denotes F, Cl, Br.
