Abstract
A process of catalytically reacting a 3-18 carbon mono-olefin such as cyclohexene with an arylhydroxide such as phenol in the liquid phase forming an ortho-alkylated arylhydroxide which is subsequently catalytically dehydrogentated to form an ortho-alkenylarylhydroxide or ortho-arylarylhydroxide such as ortho-phenylphenol.
