 Reactions:

Dibenzofuran is thermally robust with a convenient liquid range. These properties, together with its low toxicity, are exploited by the use of DBF as a heat transfer agent.

It undergoes electrophilic reactions, such as halogenation and Friedel-Crafts reactions. Reaction of DBF with bultyl lithium results in dilithiation.

Dibenzofuran is the precursor to the drug furobufen by Friedel-Crafts reaction with succinic anhydride
