ABSTRACT An improved process is provided for forming ketones from the corresponding olefins in the vapor phase in the presence of water vapor, and optionally in the additional presence of molecular oxygen, employing a heterogeneous catalyst comprising rhenium compounds and complexes containing sulfur, optionally containing at least one metal compound or complex selected from the group consisting of Group VIB metals and Group VIII noble metals, and mixtures thereof. It has been surprisingly found that these catalysts effect the formation of ketones in high selectivities with minimal selectivities to the undesirable carbon dioxide and carbon monoxide by-products.
