With specific arenes such as fluorobenzenes, the Pd-catalyzed double functionalization of C\u2013H bonds yields the desired fluoranthenes. The reaction proceeds via a palladium-catalyzed direct intermolecular arylation, followed by a direct intramolecular arylation step. As the C\u2013H bond activation of several benzene derivatives remains very challenging, the preparation of fluoranthenes from 1,8-dibromonaphthalene via Suzuki coupling followed by intramolecular C\u2013H activation has also been investigated to provide a complementary method. Using the most appropriate synthetic route and substrates, it is possible to introduce the desired functional groups at positions 7\u201310 on fluoranthenes.<\/jats:p>","DOI":"10.3762\/bjoc.20.37","type":"journal-article","created":{"date-parts":[[2024,2,23]],"date-time":"2024-02-23T03:25:56Z","timestamp":1708658756000},"page":"427-435","source":"Crossref","is-referenced-by-count":2,"title":["Mono
