Insight into Regioselective Control in Aerobic Oxidative C–H/C–H Coupling for C3-Arylation of Benzothiophenes: Toward Structurally Nontraditional OLED Materials
first isolation and X-ray characterization of a medium-sized dearomatized cyclometalated adduct involving both substrates provide extra insight into aerobicoxidative Ar–H/Ar–H cross-coupling reactions. The mechanistic breakthrough incubates the first example, enabling C–H/C–H-type C3-arylation of benzothiophenes. Finally, this chemistry is used to design blue-emitting thermally activated delayed fluorescence

Thiophene end-capped aromatic analogues, that is, naphthothiophenes, naphthodithiophenes, pyrenothiophene, and benzotrithiophene, can be prepared from commercially available hydroxyarenes in two steps, including (1) a consecutive acid-mediated nucleophilic aromatic substitution of hydroxyarenes with 2-mercaptoethanol, followed by cyclization to form an arene-fused dihydrothiophene, and (2) oxidation of the dihydrothiophene unit to thiophene.
