Article abstract of DOI:10.1246/bcsj.55.1504

In the co-existence of catalytic amount of nitrogen dioxide and oxygen, aluminum halide, titanium(IV) halide, and some other metal halides have been found to be highly selective and regiospecific halogenating agents for polycyclic aromatic compounds, including anthracene, pyrene, benzanthracene, chrysene, phenanthrene, naphthalene, triphenylene, fluoranthene, benzothiophene, and dibenzothiophene.
