Abstract

Substituted ketones are prepared by reacting a ketone containing a > CH-CO-group with an organic halide in which the halogen atom is not deactivated by attachment to an aryl nucleus or vinyl group in the presence of (1) sodium or potassium hydroxide and (2) an amine catalyst selected from inorganic nitrogen bases and their salts, primary, secondary, tertiary and quaternary aliphatic, cyclo-aliphatic and araliphatic amines, saturated mononuclear heterocyclic amines containing 5 or 6 ring atoms, 1 or 2 of said atoms being N1 or 1 N and 10, the remainder being C1 and salts of such amines (including amino acids and basic ion-exchange resins containing amino groups and their salts) and amides (including urea). Temperatures of -20 DEG to +150 DEG C. may be used. An inert organic solvent may be present. Specified suitable halides include alkyl, alkenyl, alkynyl, cycloaliphatic and aralkyl chlorides, bromides and iodides. Specified ketones include alkyl, olefinic, alicyclic and aryl ketones. The invention also comprises unsaturated ketones of formula <FORM:1059839/C2/1> where R and R3 are each C1- 6 alkyl or C2- 6 alkenyl, and R1 and R2 are each H, C1- 6 alkyl or C2- 6 alkenyl, or R1 and R2 together are C2- 6 alkylidene, and R1 and R3 together may be a trimethylene chain, with the proviso that where R1 and R2 are both H, R3 contains at least 3 C, and that where R2 is H and R1 is other than H and not linked to R3, either R3 is Me or Et and R1 is C3- 6 alkyl or C4- 6 alkenyl, or R is 4-methyl3-pentenyl, or R3 contains at least 4 C.ALSO:Perfume compositions comprise one or more unsaturated ketones of formula <FORM:1059839/A5-A6/1> where R and R3 are each C1-6 alkyl or C2-6 alkenyl and R1 and R2 are each H C1-6 alkyl or C2-6 alkenyl, or R1 and R2 together are C2-6 alkylidene, and R1 and R3 together may be a trimethylene chain, with the proviso that where R1 and R2 are both H, R3 contains at least 3C, and that where R2 is H and R1 is other than H and not linked to R3, either R3 is Me or Et and R1 is C3-6 alkyl or C4-6 alkenyl or R is 4-methyl-3-pentenyl, or R3 contains at least 4C, optionally in association with a conventional diluent and/or other odoriferous principles. A synthetic lavender composition comprises linalyl acetate, linalool, coumarin, 4,7-dimethyl-6-octen-3-one, 8-methyl-7-nonen-4-one, 6-methyl-3-ethyl-5-hepten-2-one and 2-(3-methyl -2-butenyl)-cyclopentanone.
