ABSTRACT:
A process is disclosed for selectively decarbonylating a compound of the formula ##STR1## in a mixture containing I and a compound of the formula ##STR2## wherein R is hydrogen or at least one lower alkyl group and R.sup.1 is hydrogen or a lower alkyl group. In such a process, the mixture is treated with a catalytically effective amount of a palladium catalyst to selectively decarbonylate the compound of formula I therein and the compound of formula II is recovered from the treated mixture.
