Article abstract of DOI:10.1246/bcsj.55.629

Nitration of dibenzofuran with nitric acid in trifluoroacetic acid gave 3-nitrodibenzofuran selectively under very mild conditions.In contrary, the Friedel-Crafts type nitration using alkyl nitrates and aluminium chloride in nitromethane gave 2-nitrodibenzofuran as the main product.
