Abstract
NEW MATERIAL:5-Cyclotetradecen-1-one of formula I.
USE: Perfumes. Has a strong musk scent. More volatile than the generally known 15 or 17 membered ring ketones.
PROCESS: The objective compound of formula I is obtained by heating 1-vinyl-3- cis-cyclododecen-1-ol and an alkali metal or an alkali halide in a solvent. An amide of formula II (R1, R2 are C1W3 alkyl) or formula III (R3 is C1W3 alkyl; n is 3, 4, or 5) e.g. N,N-dimethylacetoamide, N-methylpyrrolidone, etc. is used as the solvent. Na halide is preferably used as the alkali metal or halide. The reaction is carried out at 25W80°C for 2W6hr.
