Abstract
Provided is a method for producing a chlorohydrocarbon having conjugated double bonds by stereoselectively chlorinating an alcohol having conjugated double bonds. More specifically, provided is a method for producing a chlorohydrocarbon having conjugated double bonds, the method including a step of chlorinating an alcohol having conjugated double bonds with a chlorinating agent in a solvent in the presence of a base and in the absence of metal salt for chlorination of the alcohol, and the alcohol being represented by the formula (1):RCH═CHCH═CH—Z—OH  (1)wherein R represents a hydrogen atom or a linear, branched or cyclic Cmonovalent hydrocarbon group which may have at least one double bond or at least one triple bond; and Z represents a linear, branched or cyclic Cdivalent hydrocarbon group which may have at least one double bond or at least one triple bond.
