symmetrical/unsymmetrical benzo[c]furans with acenaphthylene in xylenes at reflux temperatures followed by p-toluenesulfonic acid-mediated epoxide cleavage and dehydration furnished diaryl/heteroaryl-substituted benzo[k]fluoranthenes. This strategy could be successfully applied to the synthesis of dimeric and trimeric benzo[k]fluoranthenes. Functionalization of representative benzo[k]fluoranthene derivatives
