    摘要： A fragrance composition having an excellent diffusivity and long-lasting property of fragrance and a cosmetic, toiletry, bath composition, food and drink and pharmaceutical having an excellent diffusivity and long-lasting property of fragrance by using a novel fixative. A compound represented by the following general formula (1) is incorporated in a fragrance composition or the foregoing products. The amount of the compound of the general formula (1) to be incorporated in the fragrance composition is preferably from 0.01 to 90% by weight. The amount of the compound of the general formula (1) to be incorporated directly in the foregoing products is preferably from 0.0001 to 2.0 times (by weight) the weight of the aroma composition and/or composition to be incorporated therein. In this arrangement, a fragrance composition or products having an enhanced diffusivity and long-lasting property of fragrance can be obtained without causing any safety problem on human being. wherein A represents H or OH group; B represents H or methyl group; and n represents an integer of from 0 to 2.

    摘要： 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 (I): wherein R1 represents H, a C1-C6 alkyl group which may be substituted or a C2-C6 alkenyl group which may be substituted, R2 represents a phenyl group which may have a C1-C4 alkyl group or a C1-C12 acyloxy group which may have a phenyl group or a naphthyl group, or a benzyl group or R2 is 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.
