Ruthenium-catalyzed C–H activation of thioxanthones [PDF]

Beilstein Journal of Organic Chemistry, 2015
Thioxanthones – being readily available in one step from thiosalicylic acid and arenes – were used in ruthenium-catalyzed C–H-activation reaction to produce 1-mono- or 1,8-disubstituted thioxanthones in good to excellent yields.
