Abstract
Perhydroindenyl(perhydronaphthyl)ethanones and perhydroindene(naphthalene)carboxylates differing in the size of the fused ring (C5, C6) and in the nature of carbonyl-containing substituent (acetyl, ethoxycarbonyl) undergo dehydration on heating in benzene in the presence of a catalytic amount of p-toluenesulfonic acid. The process is accompanied by complete enolization of the endocyclic oxo group. Depending on the size of the fused ring, individual partially hydrogenated naphthylethanones and naphthalene-carboxylates or mixtures of isomeric partially hydrogenated indenylethanones and indenecarboxylates are formed.
