We have been interested for some time in the aromatization to phenols of alicyclic ketones which are isomers of aromatic compounds, and in dehydrogenations leading to phenols. A palladium-carbon catalyst is the most effective agent for bringing about alicyclic-aromatic isomerizations, lS2 and this catalyst is also an extremely effective dehydrogenation agent. In order to obtain additional information about catalytic dehydrogenation as applied to ...
