ISOMERE TRIMETHYL-HEXAHYDROINDEN-DERIVATE, DEREN HERSTELLUNG UND VERWENDUNG ALS RIECHSTOFFE, SOWIE DIESE ENTHALTENDE RIECHSTOFF-KOMPOSITIONEN

摘要

The compounds disclosed are valuable odiferous substances with various shades of intense woody notes (boisambrene and styrene acetate) or intense green fragrances (petitgrain, pea, synthetic galbanum and pyrazine), together with excellent fixative qualities. They are prepared by reacting 2,2,4 (or 2,4,4)-trimethyl-1-vinylcyclopent-1-ene with 2 or 4-vinylpyridine, and can be mixed with each other or with other odiferous substances in widely varying proportions, generally in a proportion of 1 to 50 % by wt. relative to the total weight of the composition, to give new compositions.
