Thiophen Analogues of Polycyclic Aromatic Hydrocarbons

Thiophen Analogues of Anthracene and Phenantbrene.— The remaining member (237) of the thieno-analogues of anthrone-anthrol has been synthesized from the known (238) by reduction of one of the carbonyl groups to the ketal, followed by [Pg.288]

Thiophen Analogues of Polycyclic Aromatic Hydrocarbons Analogues of Anthracene and Phenanthrene. - Keto-enol tautomerism in a naphtho- and several anthra-thiophen systems [such as (241) (242)] has been studied. The system (241) (242) was obtained via the Friedel-Crafts reaction of thiophen with naphthalene-2,3-dicarboxylic anhydride followed by ring-closure. A [c] -fused system was similarly obtained by starting from... [Pg.125]
