- Ag-Cu copromoted direct C2-H bond thiolation of azoles with Bunte salts as sulfur sources
-
A direct C2-H thiolation of azoles with Bunte salts was achieved under the combined action of copper and silver salts. This protocol could furnish various substituted 2-thioazoles in moderate to good yields. This method has a broad substrate scope and shows good functional group tolerance.

- Synthetic approaches towards CGA 293'343: A novel broad-spectrum insecticide
-
Synthetic approaches towards CGA 293'343 (ISO draft common name: thiamethoxam), a novel broad-spectrum insecticide from the class neonicotinoids, are described. 2-Chloro-5-chloromethylthiazole, an important synthetic intermediate, was prepared from five different precursors. Alternatively, CGA 293'343 was prepared via the intermediate 2-benzylmercapto-5-chloromethylthiazole, the synthesis of which is also described.
