ABSTRACT:
A process for the oxidation of a compound having a terminal carbon-carbon double bond to produce the corresponding aldehyde is disclosed. In one embodiment, the process comprises contacting the compound with molecular oxygen in the presence of a Group VIII metal component initially substantially free of NO ligands and NO.sub.2 ligands in an amount effective to promote the oxidation of the compound, a reoxidation component in an amount effective to reoxidize a reduced Group VIII metal component to the Group VIII metal component and at least one alcohol selected from secondary alcohols, tertiary alcohols and mixture thereof in an amount effective to increase the aldehyde selectivity of the oxidation. The contacting occurs at conditions effective to oxidize the compound and the form the corresponding aldehyde.
