, (2016/09/12)
Provided are a method for efficiently producing an asymmetric conjugated diyne from an inexpensive and safe alternative compound to hydroxylamine hydrochloride and a method for producing a Z,Z-conjugated diene compound from the asymmetric conjugated diyne compound thus obtained. More specifically, provided is a method for producing an asymmetric conjugated diyne compound comprising a step of subjecting a terminal alkyne compound (1): HC≡C—Z1—Y1 to a coupling reaction with an alkynyl halide (2) Y2—Z2—C≡C—X by using sodium borohydride in water and an organic solvent in the presence of a copper catalyst and a base to obtain the asymmetric conjugated diyne compound (3): Y2—Z2—C≡C—C≡C—Z1—Y1. In addition, provided is a method for producing a Z,Z-conjugated diene compound by reducing the resulting asymmetric conjugated diyne compound, or the like.
