| titleOfInvention | Production of unsaturated ketones |
| abstract | Unsaturated aliphatic ketones of the general formula R1.R2.C=CH.CH2.CH2.CO.R3 wherein R1 and R2 are alkyl or alkenyl groups or H atoms and R3 is an alkyl group, are prepared by contacting allyl aceto acetates of the general formula R1.R2.C(CH=CH2).O.CO.CH2.CO.R3 at an elevated temperature, e.g. 100 DEG C.-300 DEG C., with an aluminium enolate of the general formula Al(-O.C.R4=CH.CO.R5)3 wherein one of the groups R4 and R5 is an alkyl group and the other is an alkyl or alkoxy group. Specified aluminium enolates are the tri-acetylacetonate, obtainable by reacting aluminium sulphate with acetylacetone in aqueous NH3, and a tri-(alkylacetoacetate) obtainable by reacting an aluminium tri-alkoxide with, for example, methyl or ethyl aceto acetate. Examples describe the conversion of (1) 3-methyl but-1-enyl-3-aceto acetate to 2-methylhept-2-en-6-one, the catalyst being omitted in a comparative experiment; (2) 3-methyl-pent-1-enyl-3-aceto acetate to 3-methyl-oct-3-en-7-one; and (3) linalyl aceto acetate to geranyl acetone. |
