Abstract

The alumina-catalyzed reactions of l-oxo-2, 2-dimethyl-l, 2-dihydronaphthalene(IX), l-oxo-4, 4-dimethyl-l, 4-dihydronaphthalene (X), and 1-methoxynaphthalene (111) were studied at 320420'in the presence of excess methanol. At 350'IX undergoes smooth reduction- rearrangement to form 1, 2-dimethylnaphthalene in 84-98% yield (based on IX converted) in a reaction which has a low requirement for catalyst acidity. The reactions of X are distinctly ...
