Shao, Ailong published the artcileElectrochemical Intramolecular C-H/O-H Cross-Coupling of 2-Arylbenzoic Acids, COA of Formula: C8H11BO3, the publication is Chinese Journal of Chemistry (2018), 36(7), 619-624, database is CAplus.
A synthetic protocol to lactones, e.g. I, by electro-oxidative induced C-H activation of 2-arylbenzoic acids was developed using aqueous Na2SO4 as a cheap and green supporting electrolyte in 30%-90% yields. This reaction could be conducted on a gram scale with a good efficiency as well as showed high utility for natural product synthesis like Sabilactone.
