Synthesis and Redox Behavior of 1,3-Bismethylthio-) and 1,3-Bis(phenylthio)azulenes Bearing 2- and 3-Thienyl Substituents by Palladium-Catalyzed Cross-Coupling Reaction of 2- and 6-Haloazulenes with Thienylmagnesium Ate Complexes
Preparation of thienylazulenes 3–6 was established by the palladium-catalyzed cross-coupling reaction of the corresponding haloazulenes with thienylmagnesium ate complexes, which were readily prepared from the corresponding bromothiophenes. The reaction of 3–6 with several sulfoxides in the presence of Tf2O, followed by treatment with triethylamine afforded the corresponding 1,3-bis(methylthio)- and
