METHOD OF PRODUCING ASYMMETRIC CONJUGATED DIYNE COMPOUND, AND METHOD OF PRODUCING Z,Z-CONJUGATED DIENE COMPOUND USING DIYNE COMPOUND

Japanese Patent JP2016145164

A

PROBLEM TO BE SOLVED: To provide a method of efficiently producing an asymmetric conjugated diyne compound by using an inexpensive and safe hydroxylamine hydrochloride-substituted compound, and a method of producing a Z,Z-conjugated diene compound from the obtained asymmetric conjugated diyne compound.SOLUTION: The method of producing an asymmetric conjugated diyne compound (3) Y-Z-C≡C-C≡C-Z-Yincludes at least a step of coupling a terminal alkyne compound (1) HC≡C-Z-Ywith alkynyl halide (2) Y-Z-C≡C-X in water and an organic solvent in the presence of a copper catalyst and a base by using sodium boron hydride to obtain the asymmetric conjugated diyne compound. The method of producing a Z,Z-conjugated diene compound includes a step of reducing the obtained asymmetric conjugated diyne compound, and the like.SELECTED DRAWING: None
