Efficient palladium catalyzed synthesis of heteroaromatic sulfoxides

The present Letter describes the efficient synthesis of novel heteroaromatic sulfoxides by means of a palladium catalyzed heteroarylation of sulfenate anions. Triazolopyridine, pyridine and thiophene sulfoxides can be obtained under mild conditions and in high yield from the corresponding heteroaryl bromides.

The convenient synthesis of novel heteroaromatic sulfoxides by Pd-catalyzed heteroarylation of sulfenate anions is described.
