Abstract
Unsaturated carbonyl compounds, and particularly .alpha.-substituted allylic carbonyl compounds as exemplified by 3-(1-methylallyl)-2,4-pentanedione are prepared by reacting a conjugated diolefinic compound with a compound possessing an active methylene group in the presence of certain catalytic compositions of matter at a temperature of from about -20.degree. C. to about 150.degree. C. The desired products are useful as intermediates in preparing chemical compounds which possess desirable fragrances.
