METHOD FOR PRODUCING COMPOUND HAVING BUTADIENE SKELETON CONTAINING HYDROGEN AND FLUORINE AND/OR CHLORINE

WIPO Patent Application WO/2019/151467

A1

The purpose of the present invention is to provide a method for industrially producing a compound having a polyene skeleton containing hydrogen and fluorine and/or chlorine simply and at low cost.　A method for producing a halogenated diene represented by formula (1): A1A2C=CA3–CA4=CA5A6 [In the formula: A1, A2, A5 and A6 independently represent hydrogen, fluorine or chlorine, a C1-3 (perfluoro)alkyl group or a (perfluoro)alkenyl group; A3 and A4 independently represent hydrogen, fluorine or chlorine; at least one of A1 to A6 represents hydrogen; and at least one of A1 to A6 represents fluorine or chlorine.] Furthermore, said method includes a step in which the same or different halogenated olefins undergo a coupling reaction in the presence of a zerovalent metal and metal salt, said halogenated olefins being represented by formula (2): A7A8C=CA9X [In the formula: A7 and A8 independently represent hydrogen, fluorine or chlorine, a C1-3 (perfluoro)alkyl group, or a (perfluoro)alkenyl group; A9 independently represents hydrogen, fluorine or chlorine; and X represents bromine or iodine.]
