With the view to study the significance of the 9∶10-phenanthrene double bond (“phenanthrene bridge”) in 9∶10-dimethyl-1∶2∶7∶8-dibenzanthracene (II), 6∶12-dimethylebenzo (1∶2
2∶7-Dimethoxyethylmercaptonaphthalene (IX) on cyclization gave thionaphtheno(4∶5∶4′:5′-)thionaphthene (VIII). The constitution (VIII) follows from the favoured α-cyclization in the naphthalene series and the similarity of its absorption spectrum with that of 3∶4-benzphenanthrene.
