Regioselective Palladium-Catalyzed Direct C3-H Arylation of Triazolopyridazines with Aryl Thianthrenium Salts.

A regioselective palladium-catalyzed C3-H arylation of 1,2,4-triazolo[4,3-b]pyridazines with readily accessible aryl thianthrenium salts has been developed. This method provides direct access to a diverse array of C3-arylated triazolopyridazines in moderate to excellent yields under mild and operationally simple condit...
