Abstract: The present invention relates to a method for producing dehydro rose oxide by reacting isoprenol and prenal in the presence of at least one sulfonic acid of formula R1—SO3H as catalyst, wherein R1 is selected from phenyl which carries 2 or 3 C1-C4-alkyl substituents, phenyl which carries one C8-C20-alkyl substituent and optionally also 1 or 2 C1-C4-alkyl substituents, and naphthyl which optionally carries 1 or 2 C1-C4-alkyl substituents.
