ABSTRACT:
A process for producing an .alpha.,.beta.-unsaturated ketone of the general formula ##STR1## wherein R.sub.1 represents a hydrocarbon group, R.sub.2 represents an organic group bonded through a carbon-carbon bond, R.sub.3 and R.sub.4 represent a hydrogen atom or a hydrocarbon group, and R.sub.1, R.sub.2, R.sub.3 and R.sub.4 may be linear or may form a ring when taken together in arbitrary combinations,
which comprises contacting an .alpha.-disubstituted-.beta.-keto acid ester of the general formula ##STR2## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are as defined, and R.sub.5, R.sub.6 and R.sub.7 represent a hydrogen atom or a hydrocarbon group,
with a catalyst consisting essentially of (a) a compound of a platinum-group metal and (b) and .alpha.,.omega.-alkylenedi(disubstituted)phosphine.
