Stage: PROBLEM TO BE SOLVED: To provide a method for producing a fused polycyclic compound having a fused five-membered ring that can yield an intermediate with many substituents useful as a scaffold for chemical reactions, and new p-phenylenevinylene derivatives prepared by such a production method.SOLUTION: A method for producing a fused polycyclic compound having a fused five-membered ring comprises converting a compound having a substructure represented by a general formula (1) in the figure into a compound having a substructure represented by a general formula (2) in the figure by action of an acid. In the general formula (1), R1 and R2 are each independently an alkyl group or the like, each X is independently a halogen atom, and the ring structure designated as Ar is an aromatic ring that may have substituents. In the general formula (2), R1 and R2 are each independently an alkyl group or the like, each X is independently a halogen atom, and the ring structure designated as Ar is an aromatic ring that may have substituents.SELECTED DRAWING: None (Grant)
