Abstract
A perfume composition comprising an isomeric hydroxymethyl tricyclo(5,2,1,0.sup.2,6)-decane of the formula ##STR1## wherein R.sub.1 and R.sub.2 are the hydroxymethyl CH.sub.2 OH or the formyl CHO group and R.sub.1 represents CH.sub.2 OH, when R.sub.2 is CHO and vice versa or a mixture thereof.
Claims2
An isomeric hydroxymethylformyltricyclo(5,2,1,0.sup.2.6)-decane mixture of the formula ##STR5## wherein R.sub.1 and R.sub.2 are the hydroxymethyl CH.sub.2 OH of the formyl CHO group and
- R.sub.1 represents CH.sub.2 OH, when R.sub.2 is CHO and vice versa
- wherein each component of the isomeric mixture contains both a hydroxymethyl and a formyl group and the hydroxymethyl group is in the 3, 4 or 5 position when the formyl group occupies position 8 or 9 and the formyl group is in the 3, 4 or 5 position when the hydroxymethyl group is in position 8 or 9.
