Iron catalysts in organic synthesis are strongly in demand because iron is non-toxic, inexpensive and the most abundant transition metal in the earth, although their use is still limited compared with that of rare, precious metals such as palladium, ruthenium and rhodium. This thesis describes the first practical example of iron catalysis in the carbon–hydrogen bond activation reaction to synthesized fused aromatic ring compounds.
In this report, we have described a fecl 3 -catalyzed process involving intramolecular annulation of o -phenoxy diarylacetylenes via hydroarylation to afford a series of biologically potent fused seven-membered (6–7–6) ring compounds under mild reaction conditions. This reaction was believed to proceed through friedel–crafts type sequential carbometallation followed by protonation to produce phenyldibenz [ b, f ]oxepines.

We have rationally designed a new class of alkyne‐tethered oximes and applied them in an unprecedented iron‐catalyzed radical relay protocol for the rapid assembly of a wide array of structurally new and interesting fused pyridines. This method shows broad substrate scope and good functional‐group tolerance and enabled the synthesis of several biologically active molecules.
This two-step sequence provides efficient access to diversely substituted polycyclic dibenzofuran derivatives in high yields and in an atom-efficient and environmentally friendly manner. Moreover, this strategy was also successfully used for the synthesis of a naturally occurring tetracyclic dibenzofuran, β-brazan.
An efficient iron‐catalyzed radical relay protocol enabled the rapid assembly of a wide array of structurally interesting fused pyridines from alkyne‐tethered oximes and alkenes (see scheme).
