Claims
- 1. A compound of formula ##STR35## wherein the tert-butyl radical is located in positions 5 or 6 of the aromatic ring and either (1) Y represents hydrogen; X represents a --CHO group or a group of formula ##STR36## in which symbols R', taken separately, each represent a C.sub.1 to C.sub.4 linear or branched, saturated or unsaturated alkyl radical, or taken together represent a substituted or unsubstituted C.sub.2 to C.sub.4 alkylene radical; and R.sup.2 represents a hydrogen atom or a methyl radical; or (2) X and R.sup.2 each represent a hydrogen atom and Y represents a --CH.sub.2 CHO group or a group of formula ##STR37## in which symbols R' are as defined above.
- 2. The compound of claim 1 selected from the group consisting of:
- 5-tert-butyl-2-indancarbaldehyde;
- 5-tert-butyl-2-methyl-2-indancarbaldehyde; and
- 6-tert-butyl-1-indanacetaldehyde; and
- 2-(5-tert-butyl-2-indanyl-1,3-dioxolane.
- 3. A method to confer, improve, enhance or modify the odor properties of a perfuming composition or a perfumed article, which method comprises adding to said composition or article a fragrance effective amount of a compound according to claim 1.
- 4. A method to confer, improve, enhance or modify the odor properties of a perfuming composition or a perfumed article, which method comprises adding to said composition or article a fragrance effective amount of a compound according to claim 2.
- 5. A perfuming composition or a perfumed article which contains as an active perfuming ingredient a compound according to claim 7.
- 6. A perfuming composition or a perfumed article which contains as an active perfuming ingredient a compound according to claim 2.
- 7. A perfumed article according to claim 5, in the form of a perfume, a cologne, a soap, a bath or shower gel, a shampoo or other hair-care product, a cosmetic preparation, a body deodorant or an air-freshener, a detergent or a fabric softener, or a household product.

- 9. A process for the preparation of a compound of formula ##STR38## wherein the tert-butyl radical is located in position 5 or 6 of the aromatic ring and either Y represents hydrogen and X and R.sup.2 are defined as in formula (Ia), or X and R.sup.2 represent hydrogen and Y represents a --CH.sub.2 CHO or a group of formula ##STR39## in which R' has the meaning indicated in formula (Ia), which process comprises:
- a. treating with an oxidizing agent an alcohol of formula ##STR40## to form the corresponding aldehyde (Ib); b. where applicable, methylating, in a generally known manner, the aldehyde obtained in a. which corresponds to alcohol (IVb) to form an aldehyde (Ib) of formula ##STR41## and c. where applicable, acetalizing, in a generally known manner, said aldehyde (Ib) to form the corresponding acetal.
- 10. A compound of formula ##STR42## wherein the tert-butyl radical is located in position 5 or 6 of the aromatic ring, or of formula ##STR43##
