ABSTRACT:
Disclosed is a process for producing an .alpha.,.beta.-unsaturated carbonyl compound represented by the formula [II]: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represents a hydrogen atom or a hydrocarbon residue and may be linear or may form a ring in optional combination thereof and total carbon atom number of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is 12 or less, which comprises contacting oxygen with an alkenyl compound represented by the formula [I]: ##STR2## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are as defined above and X represents a trihydrocarbylsilyl group or an acyl group in the presence of a platinum group metal-supporting catalyst.
