By using Na2SO4 aqueous solution as a cheap and green supporting electrolyte, different 2-arylbenzoic acids could provide the corresponding lactones in 30%-90% yields. This reaction could be conducted on a gram scale with a good efficiency as well as a high utility for natural product synthesis.展开更多
