Thionyl chloride-mediated chalcogenation of imidazo[1,5-a]pyridine serves as a new protocol for the synthesis of rare bisimidazopyridyl sulfides. This method provides the new route to synthesis of 2-azaindolizine sulfur-bridged dimers called chalcogenide

An aerobic copper-promoted double oxidative C–H amination and halogenation tandem reaction of 2-methylazarenes with aliphatic amines or amino acids has been developed. The reaction uses copper salts as catalysts as well as halogen sources, and molecular oxygen as the sole oxidant. This protocol is operationally simple, and gives direct access to functionalised fused imidazoles in a one-pot operation with good functional-group tolerance. The synthetic utility of the products has been tested in a Suzuki cross-coupling reaction, which proceeded in good yield.
Synthesis of 1,3-diarylated imidazo[1,5-a]pyridines with a combinatorial approach: metal-catalyzed cross-coupling reactions of 1-halo-3-arylimidazo[1,5-a]pyridines with arylmetal reagents

The halogenation of 3-arylimidazo[1,5-a]pyridines was carried out with iodine, bromine, N-chlorosuccinimide, and 1-fluoro-2,4,6-trimethylpyridinium tetrafluoroborate as halogenating agents to give selectively halogenated products 1-halo-3-arylimidazo[1,5-
