Method for producing chlorohydrocarbon having conjugated double bonds

A method for producing a chlorohydrocarbon having conjugated double bonds, the method comprising 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, wherein the alcohol is of the following formula (1):

• RCH═CHCH═CH—Z—OH (1)
• wherein R is a hydrogen atom, a linear C1-17, a branched C1-17 or a cyclic C3-17 monovalent hydrocarbon group which may have at least one double bond or at least one triple bond;
• and Z represents a linear C2-17, a branched C2-17 or a cyclic C3-17 divalent hydrocarbon group which may have at least one double bond or at least one triple bond, wherein the chlorinating agent is a sulfonyl chloride and the base is pyridine, wherein the chlorination reaction is substantially stereoselective, and wherein the amount of isomerization of the chlorohydrocarbon having conjugated double bonds is less than 10%.
