A study of the dehydrogenation of 3-methyl-5-(j3-methoxyphenyl) -2-cyclohexen-1 -one in boiling solvents with a palladium-carbon catalyst has shown that dehydrogenation to the corresponding phenol occurs readily at temperatures from 136 to 252°. Yields of 78-84% may be obtained in p-cymene, triethylbenzene and phenyl ether, with a reaction time of two hours. The corresponding omethoxyphenyl-, 2,3-dimethoxyphenyl-and 3,4dimethoxyphenylphenols were also obtained by the same procedure, in yields of 72, 70 and 86%, respectively. Philadelphia, Penna.
