PROBLEM TO BE SOLVED: To provide a method for efficiently producing conventionally hardly producible difluorobenzene derivatives having alkenyl on a side chain thereof, and to provide an intermediate usable for the production method. SOLUTION: The production method for difluorobenzene comprises steps represented by general formulae (1), (2), (3), (4), (5), (6) and (9). And each production intermediate compound thereof is provided. COPYRIGHT: (C)2008,JPO&INPIT
