    A study of the preparation of some 10-dimethylphenyl-1,2,-benzanthracenes
    Borkovec, Alexej B. (Virginia Tech, 1953-12-05)
    It is the purpose of this thesis to further investigate the reaction suggested by Bradsher, and the preparation of some 10-dimethly-phenyl-1, 2-benzanthracenes.

    Synthesis of some compounds of possible carcinogenic activity
    Borkovec, Alexej B. (Virginia Tech, 1955-06-03)
    1. The acid catalyzed cyclodehydration method was extended to the 9-aryl-1,2-benzanthracene and 9-naphthylanthracene series. 2. A new method of cyeclodehydration was described. 3. The series of 10-mono- and 10-dimethylphenyl-1,2-benzanthracenes was completed. All the isomeric 9-mono- and 9-dimethylphenyl-1,2-benzanthracenes were prepared together with the corresponding ketones. Some highly hindered ketones were prepared and their cyclization realized. A total of 47 compounds, not previously reported in the literature, were synthesized. 4. The spectra of 24 hydrocarbons were recorded and the theory of nonplanarity of these compounds substantiated.
