To provide a vinyl halide derivative which is useful as an intermediate for polyene compounds having physiological activities, such as carotenoids, and to provide a method for producing the same.
The vinyl halide derivative is represented by the general formula (1) (X1 is a halogen; A is an alkyl, an alkenyl or an alkadienyl group). The method for producing a vinyl halide derivative represented by the general formula (4) and/or the general formula (5) (Y is X2 or OR2; X1 and X2 are each identically or differently a halogen; R1 and R2 are each identically or differently a group for protecting a hydroxyl group; and the waved line E/Z is a mixture of geometrical isomers), comprises reacting an allyl halide derivative represented by the general formula (2) and/or the general formula (3) with a base.
