|Section2= |Section3= |Section4= }} Dibenzofuran is a heterocyclic organic compound with the chemical structure shown at right. It is an aromatic compound that has two benzene rings fused to a central furan ring. All the numbered carbon atoms have a hydrogen atom bonded to each of them (not shown in the image). It is a volatile white solid that is soluble in nonpolar organic solvents. It is obtained from coal tar, where it exists as a 1% component.〔Gerd Collin and Hartmut Höke "Benzofurans" in Ullmann's Encyclopedia of Industrial Chemistry, 2007, Wiley-VCH, Weinheim. 〕 ==Reactions== Dibenzofuran is extremely stable, and this property is 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.〔Ulrich Iserloh, Yoji Oderaotoshi, Shuji Kanemasa, and Dennis P.
