- Sulphones with an alcohol group and their esters
-
Sulphones of the formula: where R is alkyl, aralkyl, alkylaryl or aryl, R1 is hydrogen or -COR2 where R2 is hydrogen, alkyl or aryl, and one of X and Y is methyl and the other is hydrogen are useful for converting terpene and carotenoid compounds into the immediately higher isoprenologue, useful as perfumes, foodstuff dyes, and pharmaceuticals.
