Summary

  1. 1.

    The transformations of 2-octylnaphthalene, 2-(2-methylcyclohexenyl)naphthalene, and 2-(2-ethylcyclohexenyl)naphthalene were investigated in presence of an alumia-chromium oxide catalyst at 450°.

     
  2. 2.

    2-Octylnaphthalene suffers dehydrocyclization both at the naphthalene nucleus with formation of phenanthrene (mainly) and anthracene, and at a carbon atom of the alkyl group with formation of 11H-benzo[a]fluorene, 11H-benzo[b]fluorene, benz[a]anthracene, and chrysene.

     
  3. 3.

    The dehydrocyclization of 2-(2-methylcyclohexenyl)naphthalene gave 11H-benzo[a]fluorene and 11H-benzo[b]fluorene, and the dehydrocyclization of 2-(2-ethylcyclohexenyl)naphthalene gave 11H-benzo[a]fluorene, 11H-benzo[b]fluorene, 11-methyl-11H-benzo[a]fluorene, benz[a]anthracene, and chrysene.
