novel, simple, and efficient approach for the synthesis of benzofulvene derivatives from o‐arylaniline substrates through C−H bond activation with two diarylacetylenes as an implicit benzofulvene unit. The reactivity of synthesized benzofulvenes toward oxidation was investigated, and they were shown to transform into phenanthridines, oxabenzofulvenes, and fluorescent polycyclics.
