The invention provides a chain diene compound with desirable regioselectivity, in the presence of a specific ruthenium compound. This chain diene compound is a promising raw material for terpene. It has a structure represented by the general formula (IX): wherein R1represents H, a C1-C6alkyl group which may be substituted or a C2-C6alkenyl group which may be substituted, R2represents a phenyl group which may have a C1-C4alkyl group or a C1-C12acyloxy group which may have a phenyl group or a naphthyl group, or a benzyl group or R2is a hydroxy group which reversibly forms an aldehyde group through shifting of the position of the double bond adjacent to said hydroxy group. The chain diene compound is produced by reacting 2-substituted-1,3-butadienes with terminal olefins in the presence of a ruthenium compound in a hydrophilic solvent. Further, the above method provides an inexpensive process for preparing a mild fragrant component and a perfume composition, such as 4-methyl-5-hexen-1-al and 4-vinyl-8-methyl-7-nonenal.
