Because diarylethers are present as an important motif in pharmaceuticals and natural products, extensive studies for the development of novel methods have been conducted. A conventional method for the construction of the diarylether moiety is the intermolecular cross-coupling reaction of aryl halides and phenols with a copper or palladium catalyst. We developed a catalytic decarbonylative etherification

Arene homologation employing internal alkynes as coupling partners and 2‐pyridyloxyl as directing group through dual C−H bond functionalization was accomplished using (pentamethylcyclopentadienyl)‐rhodium(III) chloride dimer as a pre‐catalyst. This protocol proved tolerant of synthetically valuable functional groups, and provided an expeditious access to highly congested naphthalene derivatives in
The reactions of 1-unsubstituted 2-pyridones with benzyne afforded the Diels-Alder adduct, 5, 6-benzo-2-azabarrelen-3 (2H)-ones, together with a large amount of the Michael-type adduct, 2-phenoxypyridines.
