AbstractA palladium‐catalyzed intramolecular CH bond sulfuration reaction of aryl thiocarbamates has been developed. This strategy provides a new route to benzo[d][1,3]oxathiol‐2‐ones with tolerance of a wide range of substituents. Mechanistic studies suggested that the CH activation–sulfuration to afford 2‐imino‐1,3‐benzoxathiole intermediate might involve an electrophilic palladation process.magnified image

A series of ruthenium carbene catalysts containing 2‐sulfidophenolate bidentate ligand with an ortho‐substituent next to the oxygen atom were synthesized. The molecular structure of ruthenium carbene complexcontaining 2‐isopropyl‐6‐sulfidophenolate ligand was confirmed through single crystal X‐ray diffraction. An oxygen atom can be found in the opposite position of the N‐heterocyclic carbene (NHC)
