ABSTRACT:
A method for producing cyclopentadienes which comprises the step of cyclodehydration of an unsaturated carbonyl compound having a specific chemical structure in a vapor phase in the presence of a specific solid acid catalyst. The cyclopentadienes of the invention can be produced in a high yield from inexpensive starting materials through a simplified reaction process and are useful as intermediate compounds for organic synthesis.
